Classical transport in a maximally chaotic chain
William Alderson, Rémy Dubertrand, Akira Shudo
A model for a lattice of coupled cat maps has been recently introduced. This new and specific choice of the coupling makes the description especially easy and nontrivial quantities…
Universal correlations in chaotic many-body quantum states: Fock-space formulation of Berrys random wave model
Florian Schoeppl, Remy Dubertrand, Juan-Diego Urbina +1
The apparent randomness of chaotic eigenstates in interacting quantum systems hides subtle correlations dynamically imposed by their finite energy per particle. These correlations…
Critical properties of the Anderson transition in random graphs: two-parameter scaling theory, Kosterlitz-Thouless type flow and many-body localization
Ignacio García-Mata, John Martin, Olivier Giraud +3
The Anderson transition in random graphs has raised great interest, partly because of its analogy with the many-body localization (MBL) transition. Unlike the latter, many results…
Ergodic and non-ergodic many-body dynamics in strongly nonlinear lattices
Dominik Hahn, Juan-Diego Urbina, Klaus Richter +2
The study of non-linear oscillator chains in classical many-body dynamics has a storied history going back to the seminal work of Fermi, Pasta, Ulam and Tsingou (FPUT). We introduc…
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…
Analytical results for the quantum non-Markovianity of spin ensembles undergoing pure dephasing dynamics
Rémy Dubertrand, Alexandre Cesa, John Martin
We study analytically the non-Markovianity of a spin ensemble, with arbitrary number of spins and spin quantum number, undergoing a pure dephasing dynamics. The system is considere…
