Symmetry Violation of Quantum Multifractality: Gaussian fluctuations versus Algebraic Localization
A. M. Bilen, B. Georgeot, O. Giraud +2
Quantum multifractality is a fundamental property of systems such as non-interacting disordered systems at an Anderson transition and many-body systems in Hilbert space. Here we di…
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…
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…
Weak Versus Strong Disorder Superfluid-Bose Glass Transition in One Dimension
Elmer V. H. Doggen, Gabriel Lemarié, Sylvain Capponi +1
Using large-scale simulations based on matrix product state and quantum Monte Carlo techniques, we study the superfluid to Bose glass-transition for one-dimensional attractive hard…
Phase diagram of the Anderson transition with atomic matter waves
Matthias Lopez, Jean-François Clément, Gabriel Lemarié +3
We realize experimentally a cold atom system equivalent to the 3D Anderson model of disordered solids where the anisotropy can be controlled by adjusting an experimentally accessib…
Between a metal and an insulator: the critical state of the Anderson transition
Gabriel Lemarié, Hans Lignier, Dominique Delande +2
Using a three-frequency one-dimensional kicked rotor experimentally realized with a cold atomic gas, we study the transport properties at the critical point of the metal-insulator…
