text: We perform numerical simulations to study self-assembly of nanoparticles mediated
by an elastic planar surface. We show how the nontrivial elastic response to deformations
of these surfaces leads to anisotropic interactions between the particles resulting
in aggregates having different geometrical features. The morphology of the patterns
can be controlled by the mechanical properties of the surface and the strength
of the particle adhesion. We use simple scaling arguments to understand the formation
of the different structures, and we show how the adhering particles can cause
the underlying elastic substrate to wrinkle if two of its opposite edges are clamped.
Finally, we discuss the implications of our results and suggest how elastic surfaces
could be used in nanofabrication.

text: We present experimentally derived potential curves 1?and spin-orbit interaction
functions for the strongly perturbed AΣu+ 3?and bΠu states of the cesium dimer.
The results are based on data from several sources. Laser-induced fluorescence
Fourier transform spectroscopy (LIF FTS) was used some time ago in the Laboratoire
Aimé Cotton primarily to study the XΣg+ state. More recent work at Tsinghua University
provides information from moderate 3?resolution spectroscopy on the lowest levels
of the bΠ0u± state as well as additional high-resolution data. From Innsbruck
University, we have precision data obtained with cold Cs2 molecules. Recent data
from Temple University was obtained using the optical-optical double resonance
polarization spectroscopy technique, and finally, a group at the University of
Latvia has added additional LIF FTS data. In the Hamiltonian matrix, we have used
analytic potentials (the expanded Morse oscillator form) with both finite-difference
(FD) coupled-channel and discrete variable representation (DVR) calculations of
the term values. Fitted diagonal and off-diagonal spin-orbit functions are obtained
and compared with ab initio results from Temple and Moscow State universities.

text: We produce an ultracold and dense sample of rovibronic ground state Cs 2 molecules
close to the regime of quantum degeneracy, in a single hyperfine level, in the
presence of an optical lattice. The molecules are individually trapped, in the
motional ground state of an optical lattice well, with a lifetime of 8 s. For
preparation, we start with a zero-temperature atomic Mott-insulator state with
optimized double-site occupancy and efficiently associate weakly-bound dimer molecules
on a Feshbach resonance. Despite extremely weak Franck-Condon wavefunction overlap,
the molecules are subsequently transferred with >50% efficiency to the rovibronic
ground state by a stimulated four-photon process. Our results present a crucial
step towards the generation of Bose-Einstein condensates of ground-state molecules
and, when suitably generalized to polar heteronuclear molecules such as RbCs,
the realization of dipolar many-body quantum-gas phases in periodic potentials.

text: The present paper aims at finding optimal parameters for trapping of Cs 2
molecules in optical lattices, with the perspective of creating a quantum degenerate
gas of ground-state molecules. We have calculated dynamic polarizabilities of
Cs 2 molecules subject to an oscillating electric field, using accurate potential
curves and electronic transition dipole moments. We show that for some particular
wavelengths of the optical lattice, called "magic wavelengths", the
polarizability of the ground-state molecules is equal to the one of a Feshbach
molecule. As the creation of the sample of ground-state molecules relies on an
adiabatic population transfer from weakly-bound molecules created on a Feshbach
resonance, such a coincidence ensures that both the initial and final states are
favorably trapped by the lattice light, allowing optimized transfer in agreement
with the experimental observation.

text: We demonstrate the temporal Talbot effect for trapped matter waves using ultracold
atoms in an optical lattice. We investigate the phase evolution of an array of
essentially non-interacting matter waves and observe matter-wave collapse and
revival in the form of a Talbot interference pattern. By using long expansion
times, we image momentum space with sub-recoil resolution, allowing us to observe
fractional Talbot fringes up to tenth order.
