Describing the critical behavior of the Anderson transition in infinite dimension by random-matrix ensembles: logarithmic multifractality and critical localization
Weitao Chen, Olivier Giraud, Jiangbin Gong +1
Due to their analytical tractability, random matrix ensembles serve as robust platforms for exploring exotic phenomena in systems that are computationally demanding. Building on a…
Critical dynamics of long-range quantum disordered systems
Weitao Chen, Gabriel Lemarie, Jiangbin Gong
Long-range hoppings in quantum disordered systems are known to yield quantum multifractality, whose features can go beyond the characteristic properties associated with an Anderson…
Superfluidity vs prethermalisation in a nonlinear Floquet system
Sen Mu, Nicolas Macé, Jiangbin Gong +3
We show that superfluidity can be used to prevent thermalisation in a nonlinear Floquet system. Generically, periodic driving boils an interacting system to a featureless infinite…
Topological order in random interacting Ising-Majorana chains stabilized by many-body localization
Nicolas Laflorencie, Gabriel Lemarié, Nicolas Macé
We numerically explore -symmetric random interacting Ising-Majorana chains at high energy. A very rich phase diagram emerges with two topologically distinct many-body…
Engineering many-body quantum Hamiltonians with non-ergodic properties using quantum Monte Carlo
Nyayabanta Swain, Ho-Kin Tang, Darryl Chuan Wei Foo +5
We present a computational framework to identify Hamiltonians of interacting quantum many-body systems that host non-ergodic excited states. We combine quantum Monte Carlo simulati…
Two critical localization lengths in the Anderson transition on random graphs
I. García-Mata, J. Martin, R. Dubertrand +3
We present a full description of the nonergodic properties of wavefunctions on random graphs without boundary in the localized and critical regimes of the Anderson transition. We f…
Controlling symmetry and localization with an artificial gauge field in a disordered quantum system
Clément Hainaut, Isam Manai, Jean-François Clément +6
Anderson localization, the absence of diffusion in disordered media, draws its origins from the destructive interference between multiple scattering paths. The localization propert…
Chaos-assisted tunneling in the presence of Anderson localization
Elmer V. H. Doggen, Bertrand Georgeot, Gabriel Lemarié
Tunneling between two classically disconnected regular regions can be strongly affected by the presence of a chaotic sea in between. This phenomenon, known as chaos-assisted tunnel…
Return to the Origin as a Probe of Atomic Phase Coherence
Clément Hainaut, Isam Manai, Radu Chicireanu +7
We report on the observation of the coherent enhancement of the return probability ("enhanced return to the origin" , ERO) in a periodically kicked cold-atom gas. By submitting an…
Routes towards the experimental observation of the large fluctuations due to chaos assisted tunneling effects with cold atoms
R. Dubertrand, J. Billy, D. Guéry-Odelin +2
In the presence of a complex classical dynamics associated with a mixed phase space, a quantum wave function can tunnel between two stable islands through the chaotic sea, an effec…
Multifractality of quantum wave functions in the presence of perturbations
R. Dubertrand, I. García-Mata, B. Georgeot +3
We present a comprehensive study of the destruction of quantum multifractality in the presence of perturbations. We study diverse representative models displaying multifractality,…
Critical Properties of the Superfluid - Bose Glass Transition in Two Dimensions
Juan Pablo Álvarez Zúñiga, David J. Luitz, Gabriel Lemarié +1
We investigate the superfluid (SF) to Bose glass (BG) quantum phase transition using extensive quantum Monte Carlo simulations of two-dimensional hard-core bosons in a random box p…
Two scenarios for quantum multifractality breakdown
R. Dubertrand, I. García-Mata, B. Georgeot +3
We expose two scenarios for the breakdown of quantum multifractality under the effect of perturbations. In the first scenario, multifractality survives below a certain scale of the…
Universal scaling of the order-parameter distribution in strongly disordered superconductors
G. Lemarié, A. Kamlapure, D. Bucheli +6
We investigate theoretically and experimentally the statistical properties of the inhomogeneous order-parameter distribution (OPD) at the verge of the superconductor-insulator tran…
Thermal Enhancement of Interference Effects in Quantum Point Contacts
Adel Abbout, Gabriel Lemarié, Jean-Louis Pichard
We study an electron interferometer formed with a quantum point contact and a scanning probe tip in a two-dimensional electron gas. The images giving the conductance as a function…
Universality of the Anderson transition with the quasiperiodic kicked rotor
G. Lemarié, B. Grémaud, D. Delande
We report a numerical analysis of the Anderson transition in a quantum-chaotic system, the quasiperiodic kicked rotor with three incommensurate frequencies. It is shown that this d…
Experimental observation of the Anderson transition with atomic matter waves
Julien Chabé, Gabriel Lemarié, Benoît Grémaud +3
We realize experimentally an atom-optics quantum chaotic system, the quasiperiodic kicked rotor, which is equivalent to a 3D disordered system, that allow us to demonstrate the And…
