Coherent Forward Scattering Peak and Multifractality
Maxime Martinez, Gabriel Lemarié, Bertrand Georgeot +2
It has recently been shown that interference effects in disordered systems give rise to two non-trivial structures: the coherent backscattering (CBS) peak, a well-known signature o…
Chaos-Assisted Long-Range Tunneling for Quantum Simulation
Maxime Martinez, Olivier Giraud, Denis Ullmo +4
We present an extension of the chaos-assisted tunneling mechanism to spatially periodic lattice systems. We demonstrate that driving such lattice systems in an intermediate regime…
Dirty bosons on the Cayley tree: Bose-Einstein condensation versus ergodicity breaking
Maxime Dupont, Nicolas Laflorencie, Gabriel Lemarié
Building on large-scale quantum Monte Carlo simulations, we investigate the zero-temperature phase diagram of hard-core bosons in a random potential on site-centered Cayley trees w…
Chain breaking and Kosterlitz-Thouless scaling at the many-body localization transition in the random field Heisenberg spin chain
Nicolas Laflorencie, Gabriel Lemarié, Nicolas Macé
Despite tremendous theoretical efforts to understand subtleties of the many-body localization (MBL) transition, many questions remain open, in particular concerning its critical pr…
Chaos-assisted tunneling resonances in a synthetic Floquet superlattice
M. Arnal, G. Chatelain, M. Martinez +7
The field of quantum simulation, which aims at using a tunable quantum system to simulate another, has been developing fast in the past years as an alternative to the all-purpose q…
