Observing the emergence of a velocity hierarchy in matter waves
Xudong Yu, Wenhan Chen, Igor Zhuravlev +8
Classical waves in dispersive media naturally exhibit distinct phase and group velocities. Whether an analogous separation of velocities can emerge in matter waves under strong man…
Universal scaling of many-body effects in quantum tunneling
Hongmian Shui, Chi-Kin Lai, Chengyang Wu +6
Quantum tunneling is fundamental to diverse phenomena and underpins a wide range of modern technologies. In the study of superconducting quantum computation and high-temperature su…
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…
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…
Interaction dependence of the Hall response for the Bose-Hubbard triangular ladder
Catalin-Mihai Halati, Thierry Giamarchi
We explore the behavior of the Hall response of a Bose-Hubbard triangular ladder in a magnetic field as a function of the repulsive on-site atomic interactions. We consider a wide…
