Quantum atomic and molecular gases are flexible systems for studies of fundamental many-
body physics. They have traditionally been produced in harmonic electromagnetic traps and …

The density-matrix renormalization group (DMRG) is a numerical algorithm for the efficient
truncation of the Hilbert space of low-dimensional strongly correlated quantum systems …

There is a pressing need for robust and straightforward methods to create potentials for
trapping Bose–Einstein condensates (BECs) that are simultaneously dynamic, fully arbitrary …

In recent years, various methods have been developed to generate laser beams with zero
central intensity such as Laguerre-Gaussian beams, high-order Bessel-Gaussian beams …

One of the central paradigms for classical and quantum chaos in conservative systems is the
two-dimensional billiard in which particles are confined to a closed region in the plane …

We report on experimental observations of chaotic and regular motion of ultracold atoms
confined by a billiard-shaped optical dipole potential induced by a rapidly scanning laser …

We discuss the application of spatial light modulators (SLMs) to the field of atom optics. We
show that SLMs may be used to generate a wide variety of optical potentials that are useful …

We report on the local probing and preparation of an ultracold Fermi gas on the length scale
of one micrometer, ie of the order of the Fermi wavelength. The essential tool of our …

A new technique is proposed for generating a tight dark focal spot surrounded by uniform
light intensity in all directions. It is based on a single focusing lens illuminated from one side …

By using the worldline Monte Carlo technique, matrix product state, and a variational
approach à la Feynman, we investigate the equilibrium properties and relaxation features of …
