Mass Dependence of Ultracold Three-Body Collision Rates

open access: yes, 2005
We show that many aspects of ultracold three-body collisions can be controlled by choosing the mass ratio between the collision partners. In the ultracold regime, the scattering length dependence of the three-body rates can be substantially modified from

Entanglement in dissipative dynamics of identical particles

open access: yes, 2013
Entanglement of identical massive particles recently gained attention, because of its relevance in highly controllable systems, e.g. ultracold gases.

Quantum gas microscopy of ytterbium: cool me twice

open access: yesNew Journal of Physics, 2016
The site-resolved detection of ultracold atoms in optical lattice potentials is a powerful technique to study lattice models of correlated quantum matter. In their recent paper, Yamamoto et al (2016 New J. Phys.

Light trapping in high-density ultracold atomic gases for quantum memory applications

open access: yes, 2010
High-density and ultracold atomic gases have emerged as promising media for storage of individual photons for quantum memory applications. In this paper we provide an overview of our theoretical and experimental efforts in this direction, with particular

Cavity-Assisted Generation of Sustainable Macroscopic Entanglement of Ultracold Gases

open access: yesAtoms, 2015
Prospects for reaching persistent entanglement between two spatially-separated atomic Bose–Einstein condensates are outlined. The system setup comprises two condensates loaded in an optical lattice, which, in return, is confined within a high-Q optical ...

Ultra-cold single-atom quantum heat engines

open access: yesNew Journal of Physics, 2019
We propose a scheme for a single-atom quantum heat engine based on ultra-cold atom technologies. Building on the high degree of control typical of cold atom systems, we demonstrate that three paradigmatic heat engines—Carnot, Otto and Diesel—are within ...

Ultracold atomic quantum gases far from equilibrium

open access: yes, 2006
We calculate the time evolution of a far-from-equilibrium initial state of a non-relativistic ultracold Bose gas in one spatial dimension. The non-perturbative approximation scheme is based on a systematic expansion of the two-particle irreducible ...

Density-induced geometric frustration of ultra-cold bosons in optical lattices

open access: yesNew Journal of Physics, 2016
A density-dependent gauge field may induce density-induced geometric frustration, leading to a non-trivial interplay between density modulation and frustration, which we illustrate for the particular case of ultra-cold bosons in zig-zag optical lattices ...

Imaging the collective excitations of an ultracold gas using statistical correlations

open access: yesNew Journal of Physics, 2014
Advanced data analysis techniques have proved to be crucial for extracting information from noisy images. Here we show that principal component analysis can be successfully applied to ultracold gases to unveil their collective excitations.
