Pure gapped ground states of spin chains are short-range entangled
Wojciech De Roeck, Martin Fraas, Bruno de O. Carvalho
We consider spin chains with a finite range Hamiltonian. For reasons of simplicity, the chain is taken to be infinitely long. A ground state is said to be a unique gapped ground st…
Many-body Localization and Poisson statistics in the Quantum Sun model
Wojciech De Roeck, Amirali Hannani
The Quantum Sun model is a many-body Hamiltonian model of interacting spins arranged on the half-line (or the line). Spins at distance from the origin are coupled to the rest o…
A Rigorous Theory of Prethermalization without Temperature
Wen Wei Ho, Wojciech De Roeck
Prethermalization refers to the physical phenomenon where a system evolves toward some long-lived non-equilibrium steady state before eventual thermalization sets in. One general s…
Very slow heating for weakly driven quantum many-body systems
Wojciech De Roeck, Victor Verreet
It is well understood that many-body systems driven at high frequency heat up only exponentially slowly and exhibit a long prethermalization regime. We prove rigorously that a cert…
Glassy dynamics in strongly anharmonic chains of oscillators
Wojciech De Roeck, François Huveneers
We review the mechanism for transport in strongly anharmonic chains of oscillators near the atomic limit where all oscillators are decoupled. In this regime, the motion of most osc…
Note on linear response for interacting Hall insulators
Sven Bachmann, Alex Bols, Wojciech De Roeck +1
We relate explicitly the adiabatic curvature -- in flux space -- of an interacting Hall insulator with nondegenerate ground state to various linear response coefficients, in partic…
