Hi subscribers,

My apologies for the lateness of this week's email. The semester started here
at the beginning of last week, and this year I've had some previously unfamiliar
duties that have soaked up all my time and then some. Firstly I developed a
contextualised lab on projectile motion based around frogs (for the biologists),
and then I've had to pick up supervising the proper first year physics labs on
top of running our stat mech course. It's been interesting given that I think
the last time I tried to do some experimental physics was some saturated
absorption spectroscopy in my own undergraduate degree. (Apart from being the
person looking through the IR viewer when we first got the Rb MOT running in the
UQ lab back in 2002, which doesn't really count I think!)

This week (well, almost two weeks ago) sees 18 new abstracts, and 18
replacements:

Title: Introduction to FFLO phases and collective mode in the BEC-BCS crossover
Authors: R.Combescot
Categories: cond-mat.supr-con cond-mat.soft
Comments: 20 pages, to be published in the Proceedings of the 2006 Enrico Fermi
Summer School on "Ultracold Fermi gases", organized by M. Inguscio, W.
Ketterle and C.Salomon (Varenna, Italy, June 2006)
Subj-class: Superconductivity; Soft Condensed Matter
\\
The main focus of this paper is a discussion of what might happen in a BCS
superfluid when there is an imbalance between the two populations of fermionic
particles forming Cooper pairs, having in mind the case of ultracold Fermi
gases. In the last part the evolution in the BEC-BCS crossover of the
collective mode arising in such a superfluid (with balanced atomic populations)
is briefly considered.

Title: Trapping and observing single atoms in the dark
Authors: T. Puppe, I. Schuster, A. Grothe, A. Kubanek, K. Murr, P.W.H. Pinkse,
and G. Rempe
Categories: quant-ph
\\
A single atom strongly coupled to a cavity mode is stored by
three-dimensional confinement in blue-detuned cavity modes of different
longitudinal and transversal order. The vanishing light intensity at the trap
center reduces the light shift of all atomic energy levels. This is exploited
to detect a single atom by means of a dispersive measurement with 90%
confidence in 0.030 ms, limited by the photon-detection efficiency. As the atom
switches resonant cavity transmission into cavity reflection, the atom can be
detected while scattering only a few spontaneous photons.

Title: Enhanced Spontaneous Emission Into The Mode Of A Cavity QED System
Authors: M. L. Terraciano, R. Olson Knell, D. L. Freimund, L. A. Orozco, J. P.
Clemens, and P. R. Rice
Categories: quant-ph
Comments: 9 pages, 2 figures, to appear in May 2007 Optics Letters
\\
We study the light generated by spontaneous emission into a mode of a cavity
QED system under weak excitation of the orthogonally polarized mode. Operating
in the intermediate regime of cavity QED with comparable coherent and
decoherent coupling constants, we find an enhancement of the emission into the
undriven cavity mode by more than a factor of 18.5 over that expected by the
solid angle subtended by the mode. A model that incorporates three atomic
levels and two polarization modes quantitatively explains the observations.

Title: Quantum states for Heisenberg limited interferometry
Authors: H. Uys and P. Meystre
Categories: quant-ph
\\
The phase resolution of interferometers is limited by the so-called
Heisenberg limit, which states that the optimum phase sensitivity is inversely
proportional to the number of interfering particles $N$, a $1/\sqrt{N}$
improvement over the standard quantum limit. We have used simulated annealing,
a global optimization strategy, to systematically search for quantum
interferometer input states that approach the Heisenberg limited uncertainty in
estimates of the interferometer phase shift. We compare the performance of
these states to that of other non-classical states already known to yield
Heisenberg limited uncertainty.

Title: On the Transport of Atomic Ions in Linear and Multidimensional Ion Trap
Arrays
Authors: D. Hucul, M. Yeo, S. Olmschenk, C. Monroe, W.K. Hensinger, J. Rabchuk
Categories: quant-ph
\\
Trapped atomic ions have become one of the most promising architectures for a
quantum computer, and current effort is now devoted to the transport of trapped
ions through complex segmented ion trap structures in order to scale up to much
larger numbers of trapped ion qubits. This paper covers several important
issues relevant to ion transport in any type of complex multidimensional rf
(Paul) ion trap array. We develop a general theoretical framework for the
application of time-dependent electric fields to shuttle laser-cooled ions
along any desired trajectory, and describe a method for determining the effect
of arbitrary shuttling schedules on the quantum state of trapped ion motion. In
addition to the general case of linear shuttling over short distances, we
introduce issues particular to the shuttling through multidimensional
junctions, which are required for the arbitrary control of the positions of
large arrays of trapped ions. This includes the transport of ions around a
corner, through a cross or T junction, and the swapping of positions of
multiple ions in a laser-cooled crystal. Where possible, we make connection to
recent experimental results in a multidimensional T junction trap, where
arbitrary 2-dimensional transport was realized.

Title: Quantum theory of degenerate $\chi^{(3)}$ two-photon state
Authors: Jun Chen, Kim Fook Lee, and Prem Kumar
Categories: quant-ph
\\
We developed a quantum theory for degenerate $\chi^{(3)}$ two-photon state
generated from optical fiber, and compared the theory predictions with an
experimental result which exhibits a Hong-Ou-Mandel dip visibility of around
94%. Excellent agreement between theory and experiment has been achieved, and
we attribute the missing 6% visibility mainly to spatial mode mismatch between
signal and idler photons at the beamsplitter.

Title: Mass flows and angular momentum density for $p_x+ip_y$ paired fermions
in a harmonic trap
Authors: Michael Stone, Inaki Anduaga
Categories: cond-mat.supr-con
Subj-class: Superconductivity
\\
We present a simple two-dimensional model of a $p_x+ip_y$ superfluid in which
the mass flow that gives rise to the intrinsic angular momentum is easily
calculated by numerical diagonalization of the Bogoliubov-de Gennes operator.
We find that, at zero temperature and for constant director $\bf l$, the mass
flow closely follows the Ishikawa-Mermin-Muzikar formula ${\bf j}_{\rm mass}= \frac 12 {\rm curl} (\rho \hbar {\bf l}/2)$.

Title: Excitations in a non-equilibrium Bose-Einstein condensate of
exciton-polaritons
Authors: M. Wouters and I. Carusotto
Categories: cond-mat.other
Subj-class: Other
\\
We have developed a mean-field model to describe the dynamics of a
non-equilibrium Bose-Einstein condensate of exciton-polaritons in a
semiconductor microcavity. The spectrum of elementary excitations around the
stationary state is analytically studied in different geometries. A diffusive
behaviour of the Goldstone mode is found in the spatially homogeneous case and
new features are predicted for the Josephson effect in a two-well geometry.

Title: Magneto-electrostatic trapping of ground state OH molecules

Categories: physics.atom-ph physics.chem-ph
Subj-class: Atomic Physics; Chemical Physics
\\
We report the magnetic confinement of neutral, ground state hydroxyl radicals
(OH) at a density of $\sim3\times10^{3}$ cm$^{-3}$ and temperature of $\sim$30
mK. An adjustable electric field of sufficient magnitude to polarize the OH is
superimposed on the trap in either a quadrupole or homogenous field geometry.
The OH is confined by an overall potential established via molecular state
mixing induced by the combined electric and magnetic fields acting on the
molecule's electric dipole and magnetic dipole moments, respectively. An
effective molecular Hamiltonian including Stark and Zeeman terms has been
constructed to describe single molecule dynamics inside the trap. Monte Carlo
simulation using this Hamiltonian accurately models the observed trap dynamics
in various trap configurations. Confinement of cold polar molecules in a
magnetic trap, leaving large, adjustable electric fields for control, is an
important step towards the study of low energy dipole-dipole collisions.

Title: Planar Atom Trap and Magnetic Resonance 'Lens' Designs

Categories: physics.atom-ph physics.med-ph
Comments: 19 text pages, 8 figures
Subj-class: Atomic Physics; Medical Physics
\\
We present various planar magnetic designs that create points above the plane
where the magnitude of the static magnetic field is a local minimum. Structures
with these properties are of interest in the disciplines of neutral atom
confinement, magnetic levitation, and magnetic resonance imaging. Each planar
permanent magnet design is accompanied by the equivalent planar single
non-crossing conductor design. Presented designs fall into three categories
producing: a) zero value magnetic field magnitude point minima, b) non-zero
magnetic field magnitude point minima requiring external bias magnetic field,
and c) self-biased non-zero magnetic field magnitude point minima. We also
introduce the Principle of Amperean Current Doubling in planar perpendicularly
magnetized thin films that can be used to improve the performance of each
permanent magnet design we present. Single conductor current-carrying designs
are suitable for single layer lithographic fabrication, as we experimentally
demonstrate. Finally, we present the case that nanometer scale recording of
perpendicular anisotropy thin magnetic films using presently available data
storage technology can provide the ultimate miniaturization of the presented
designs.

Title: Semiclassical quantization of the Bogoliubov spectrum
Authors: Andrey R. Kolovsky
Categories: cond-mat.stat-mech
Subj-class: Statistical Mechanics
\\
We analyze the Bogoliubov spectrum of the 3-sites Bose-Hubbard model with
finite number of Bose particles by using a semiclassical approach. The
Bogoliubov spectrum is shown to be associated with the low-energy regular
component of the classical Hubbard model. We identify the full set of the
integrals of motions of this regular component and, quantizing them, obtain the
energy levels of the quantum system. The critical values of the energy, above
which the regular Bogoliubov spectrum evolves into a chaotic spectrum, is
indicated as well.

We describe three-body collisions in the resonant regime close to a Feshbach
resonance by taking fully into account two-body scattering processes occurring
in both the open and closed channels.
We extract the temperature dependence of the three-body recombination rate,
and find very good agreement with the experimental results of Kraemer et al.
[Nature 440, 315 (2006)] that recently provided the first convincing
observation of Efimov physics.
In addition, we obtain the atom-dimer scattering length, that may be of
relevance in future experiments.

Title: Spin Drag and Spin-Charge Separation in Cold Fermi Gases
Authors: Marco Polini and Giovanni Vignale
Categories: cond-mat.str-el
Comments: 4 pages, 4 figures, submitted
Subj-class: Strongly Correlated Electrons
\\
Low-energy spin and charge excitations of one-dimensional interacting
fermions are completely decoupled and propagate with different velocities.
These modes however can decay due to several possible mechanisms. In this paper
we expose a new facet of spin-charge separation: not only the speeds but also
the damping rates of spin and charge excitations are different. While the
propagation of long-wavelength charge excitations is essentially ballistic,
spin propagation is intrinsically damped and diffusive. We suggest that cold
Fermi gases trapped inside a tight atomic waveguide offer the opportunity to
measure the spin-drag relaxation rate that controls the broadening of a spin
packet.

Title: Light scattering from ultracold atoms in optical lattices as an optical
probe of quantum statistics
Authors: Igor B. Mekhov, Christoph Maschler, Helmut Ritsch
Categories: quant-ph
\\
We study off-resonant collective light scattering from ultracold atoms
trapped in an optical lattice. Scattering from different atomic quantum states
creates different quantum states of the scattered light, which can be
distinguished by measurements of the spatial intensity distribution, quadrature
variances, photon statistics, or spectral measurements. In particular,
angle-resolved intensity measurements reflect global statistics of atoms (total
number of radiating atoms) as well as local statistical quantities (single-site
statistics even without an optical access to a single site) and pair
correlations between different sites. As a striking example we consider
scattering from transversally illuminated atoms into an optical cavity mode.
For the Mott insulator state, similar to classical diffraction, the number of
photons scattered into a cavity is zero due to destructive interference, while
for the superfluid state it is nonzero and proportional to the number of atoms.
Moreover, we demonstrate that light scattering into a standing-wave cavity has
a nontrivial angle dependence, including the appearance of narrow features at
angles, where classical diffraction predicts zero.

Title: The degenerate Fermi gas with renormalized density-dependent
interactions in the K harmonic approximation
Authors: Seth T. Rittenhouse and Chris H. Greene (Dept. of Physics and JILA
Categories: physics.atom-ph
Comments: 23 pages, 8 figures, submitted to PRA
Subj-class: Atomic Physics
\\
We present a simple implementation of a density-dependent, zero-range
interactions in a degenerate Fermi gas described in hyperspherical coordinates.
The method produces a 1D effective potential which accurately describes the
ground state energy as a function of the hyperradius, the rms radius of the two
spin component gas throughout the unitarity regime. In the unitarity regime the
breathing mode frequency is found to limit to the non-interacting value. A
dynamical instability, similar to the Bosenova, is predicted to be possible in
gases containing more than three spin components, for large, negative, two-body
scattering lengths.

\\
The short-term stability of passive atomic frequency standards, especially in
pulsed operation, is often limited by local oscillator noise via
intermodulation effects. We present an experimental demonstration of the
intermodulation effect on the frequency stability of a continuous atomic
fountain clock where, under normal operating conditions, it is usually too
small to observe. To achieve this, we deliberately degrade the phase stability
of the microwave field interrogating the clock transition. We measure the
frequency stability of the locked, commercial-grade local oscillator, for two
modulation schemes of the microwave field: square-wave phase modulation and
square-wave frequency modulation. We observe a degradation of the stability
whose dependence with the modulation frequency reproduces the theoretical
predictions for the intermodulation effect. In particular no observable
degradation occurs when this frequency equals the Ramsey linewidth.
presently equal to 2x10-13 at 1s, is limited by atomic shot-noise and therefore
could be reduced were the atomic flux increased.

Results of theoretical calculations of ionization rates of Rb and Na Rydberg
atoms by blackbody radiation (BBR) are presented. Calculations have been
performed for nS, nP and nD states of Na and Rb, which are commonly used in a
variety of experiments, at principal quantum numbers n=8-65 and at three
ambient temperatures of 77, 300 and 600 K. A peculiarity of our calculations is
that we take into account the contributions of BBR-induced redistribution of
population between Rydberg states prior to photoionization and field ionization
by extraction electric field pulses. The obtained results show that these
phenomena affect both the magnitude of measured ionization rates and shapes of
their dependencies on n. The calculated ionization rates are compared with the
results of our earlier measurements of BBR-induced ionization rates of Na nS
and nD Rydberg states with n=8-20 at 300 K. A good agreement for all states
except nS with n>15 is observed. We also present the useful analytical formulae
for quick estimation of BBR ionization rates of Rydberg atoms.
