Locality and nonlocality of classical restrictions of quantum spin systems with applications to quantum large deviations and entanglement
Wojciech De Roeck, Christian Maes, Karel Netočný +1
We study the projection on classical spins starting from quantum equilibria. We show Gibbsianness or quasi-locality of the resulting classical spin system for a class of gapped qua…
Quantum Diffusion with Drift and the Einstein Relation II
Wojciech De Roeck, Juerg Froehlich, Kevin Schnelli
This paper is a companion to 'Quantum Diffusion with Drift and the Einstein Relation I' (jointly submitted to arXiv). Its purpose is to describe and prove a certain number of techn…
Quantum Diffusion with Drift and the Einstein Relation I
Wojciech De Roeck, Juerg Froehlich, Kevin Schnelli
We study the dynamics of a quantum particle hopping on a simple cubic lattice and driven by a constant external force. It is coupled to an array of identical, independent thermal r…
Minimal velocity estimates and soft mode bounds for the massless spin-boson model
W. De Roeck, A. Kupiainen
We consider generalised versions of the spin-boson model at small coupling. We assume the spin (or atom) to sit at the origin and the propagation speed o…
