Slow dissipation and spreading in disordered classical systems: A direct comparison between numerics and mathematical bounds
Wojciech De Roeck, François Huveneers, Oskar A. Prośniak
We study the breakdown of Anderson localization in the one-dimensional nonlinear Klein-Gordon chain, a prototypical example of a disordered classical many-body system. A series of…
Similarity between a many-body quantum avalanche model and the ultrametric random matrix model
Jan Šuntajs, Miroslav Hopjan, Wojciech De Roeck +1
In the field of ergodicity-breaking phases, it has been recognized that quantum avalanches can destabilize many-body localization at a wide range of disorder strengths. This has in…
Step Heat Profile in Localized Chains
Wojciech De Roeck, Abhishek Dhar, Francois Huveneers +1
We consider two types of strongly disordered one-dimensional Hamiltonian systems coupled to baths (energy or particle reservoirs) at the boundaries: strongly disordered quantum spi…
Effective Hamiltonians, prethermalization and slow energy absorption in periodically driven many-body systems
D. A. Abanin, W. De Roeck, W. W. Ho +1
We establish some general dynamical properties of lattice many-body systems that are subject to a high-frequency periodic driving. We prove that such systems have a quasi-conserved…
Exponentially slow heating in periodically driven many-body systems
Dmitry Abanin, Wojciech De Roeck, François Huveneers
We derive general bounds on the linear response energy absorption rates of periodically driven many-body systems of spins or fermions on a lattice. We show that for systems with lo…
Can translation invariant systems exhibit a Many-Body Localized phase?
Wojciech De Roeck, François Huveneers
This note is based on a talk by one of us, F. H., at the conference PSPDE II, Minho 2013. We review some of our recent works related to (the possibility of) Many-Body Localization…
Scenario for delocalization in translation invariant systems
Wojciech De Roeck, Francois Huveneers
We investigate the possibility of Many-Body Localization in translation invariant Hamiltonian systems, which was recently brought up by several authors. A key feature of Many-Body…
Asymptotic quantum many-body localization from thermal disorder
Wojciech De Roeck, François Huveneers
We consider a quantum lattice system with infinite-dimensional on-site Hilbert space, very similar to the Bose-Hubbard model. We investigate many-body localization in this model, i…
Asymptotic localization of energy in non-disordered oscillator chains
Wojciech De Roeck, François Huveneers
We study two popular one-dimensional chains of classical anharmonic oscillators: the rotor chain and a version of the discrete non-linear Schrödinger chain. We assume that the inte…
Fluctuations of Quantum Currents and Unravelings of Master Equations
Jan Derezinski, Wojciech De Roeck, Christian Maes
The very notion of a current fluctuation is problematic in the quantum context. We study that problem in the context of nonequilibrium statistical mechanics, both in a microscopic…
Symmetries of the ratchet current
Wojciech De Roeck, Christian Maes
Recent advances in nonequilibrium statistical mechanics shed new light on the ratchet effect. The ratchet motion can thus be understood in terms of symmetry (breaking) consideratio…
H-Theorems from Autonomous Equations
W. De Roeck, C. Maes, K. Netocny
The H-theorem is an extension of the Second Law to a time-sequence of states that need not be equilibrium ones. In this paper we review and we rigorously establish the connection w…
