Dynamic Kosterlitz-Thouless transition in 2D Bose mixtures of ultra-cold atoms
L. Mathey, Kenneth J. Günter, Jean Dalibard +1
We propose a realistic experiment to demonstrate a dynamic Kosterlitz-Thouless transition in ultra-cold atomic gases in two dimensions. With a numerical implementation of the Trunc…
Exploring the thermodynamics of a two-dimensional Bose gas
Tarik Yefsah, Rémi Desbuquois, Lauriane Chomaz +2
Using \emph{in situ} measurements on a quasi two-dimensional, harmonically trapped Rb gas, we infer various equations of state for the equivalent homogeneous fluid. From the…
Strongly correlated states of a small cold atomic cloud from geometric gauge fields
B. Juliá-Díaz, D. Dagnino, K. J. Günter +4
Using exact diagonalization for a small system of cold bosonic atoms, we analyze the emergence of strongly correlated states in the presence of an artificial magnetic field. This g…
Dynamics and Thermodynamics of the Low-Temperature Strongly Interacting Bose Gas
Nir Navon, Swann Piatecki, Kenneth John Günter +5
We measure the zero-temperature equation of state of a homogeneous Bose gas of Li atoms by analyzing the \emph{in-situ} density distributions of trapped samples. For increasing…
The equilibrium state of a trapped two-dimensional Bose gas
Steffen P. Rath, Tarik Yefsah, Kenneth J. Guenter +5
We study experimentally and numerically the equilibrium density profiles of a trapped two-dimensional Rb Bose gas, and investigate the equation of state of the homogeneous s…
A Mott insulator of fermionic atoms in an optical lattice
Robert Jördens, Niels Strohmaier, Kenneth Günter +2
In a solid material strong interactions between the electrons can lead to surprising properties. A prime example is the Mott insulator, where the suppression of conductivity is a r…
