Leggett's bound and superfluidity in strongly interacting bosons
Lorenzo Pizzino, Haocong Pan, Thierry Giamarchi +1
A density-based superfluid bound called Leggett's bound has been proved to be a good estimator of the superfluid fraction for cold atomic gases in the mean-field regime. Here, we i…
Steady state diagram of interacting fermionic atoms coupled to dissipative cavities
Luisa Tolle, Ameneh Sheikhan, Thierry Giamarchi +2
We investigate fermionic atoms subjected to an optical lattice and coupled to a high finesse optical cavity with photon losses. A transverse pump beam introduces a coupling between…
Probing universal phase diagram of dimensional crossover with an atomic quantum simulator
Jinyuan Tian, Zhongcheng Yu, Jing Liu +7
Dimensionality is a fundamental concept in physics, which plays a hidden but crucial role in various domains, including condensed matter physics, relativity and string theory, stat…
Universal low-density power laws of the dc conductivity and Hall constant in the self-consistent Born approximation
Giacomo Morpurgo, Christophe Berthod, Thierry Giamarchi
The dc conductivity tensor of two-dimensional one-band metals with weak pointlike disorder and magnetic field is studied in the self-consistent Born approximation, with special emp…
Measuring Hall voltage and Hall resistance in an atom-based quantum simulator
T. -W. Zhou, T. Beller, G. Masini +7
In the Hall effect, a voltage drop develops perpendicularly to the current flow in the presence of a magnetic field, leading to a transverse Hall resistance. Recent developments wi…
