Probing symmetries of quantum many-body systems through gap ratio statistics
Olivier Giraud, Nicolas Macé, Eric Vernier +1
The statistics of gap ratios between consecutive energy levels is a widely used tool, in particular in the context of many-body physics, to distinguish between chaotic and integrab…
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…
Quantum circuit at criticality
Nicolas Macé
We study a simple quantum circuit model which, without need for fine tuning, is very close to sitting at the transition between ergodic and many-body localized (MBL) phases. We pro…
From eigenstate to Hamiltonian: Prospects for ergodicity and localization
Maxime Dupont, Nicolas Macé, Nicolas Laflorencie
This paper addresses the so-called inverse problem which consists in searching for (possibly multiple) parent target Hamiltonian(s), given a single quantum state as input. Starting…
Multifractal Scalings across the Many-Body Localization Transition
Nicolas Macé, Fabien Alet, Nicolas Laflorencie
In contrast with Anderson localization where a genuine localization is observed in real space, the many-body localization (MBL) problem is much less understood in the Hilbert space…
Many-body localization in a quasiperiodic Fibonacci chain
Nicolas Macé, Nicolas Laflorencie, Fabien Alet
We study the many-body localization (MBL) properties of a chain of interacting fermions subject to a quasiperiodic potential such that the non-interacting chain is always delocaliz…
