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…
Localization Transition for Interacting Quantum Particles in Colored-Noise Disorder
Giacomo Morpurgo, Laurent Sanchez-Palencia, Thierry Giamarchi
We investigate the localization transition of interacting particles in a one-dimensional correlated disorder system. The disorder which we investigate allows for vanishing backward…
Strong enhancements to superconducting properties of 1D systems from metallic reservoirs
J. E. Ebot, Sam Mardazad, Lorenzo Pizzino +3
Using a 1D bilayer system comprised of pairing and metallic layers, the present work proves the striking power of reservoir-mediated boosting of superconductivity. Employing many-b…
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…
Fluctuation-Induced Bistability of Fermionic Atoms Coupled to a Dissipative Cavity
Luisa Tolle, Ameneh Sheikhan, Thierry Giamarchi +2
We investigate the steady state phase diagram of fermionic atoms subjected to an optical lattice and coupled to a high finesse optical cavity with photon losses. The coupling betwe…
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…
Finite size analysis for interacting bosons at the 2D-1D Dimensional Crossover
Lorenzo Pizzino, Hepeng Yao, Thierry Giamarchi
In this work, we extend the analysis of interacting bosons at 2D-1D dimensional crossover for finite size and temperature by using field-theory approach (bosonization) and quantum…
Dynamical Instabilities of Strongly Interacting Ultracold Fermions in an Optical Cavity
Filip Marijanović, Sambuddha Chattopadhyay, Luka Skolc +6
Recent quench experiments on ultra cold fermions in optical cavities provide a clean platform for studying how long-range interactions between fermions structure their dynamics. Mo…
Exploring Frustration Effects of Strongly Interacting Bosons via the Hall Response

Mott transition for a Lieb-Liniger gas in a shallow quasiperiodic potential: Delocalization induced by disorder
Hepeng Yao, Luca Tanzi, Laurent Sanchez-Palencia +3
Disorder or quasi-disorder is known to favor the localization in many-body Bose systems. Here in contrast, we demonstrate an anomalous delocalization effect induced by incommensura…
