Light cones for open quantum systems
Sébastien Breteaux, Jérémy Faupin, Marius Lemm +3
We consider Markovian open quantum dynamics (MOQD). We show that, up to small-probability tails, the supports of quantum states evolving under such dynamics propagate with finite s…
Maximal Speed of Propagation in Open Quantum Systems
Sébastien Breteaux, Jérémy Faupin, Marius Lemm +1
We prove a maximal velocity bound for the dynamics of Markovian open quantum systems. The dynamics are described by one-parameter semi-groups of quantum channels satisfying the von…
Maximal speed for macroscopic particle transport in the Bose-Hubbard model
Jérémy Faupin, Marius Lemm, Israel Michael Sigal
The Lieb-Robinson bound asserts the existence of a maximal propagation speed for the quantum dynamics of lattice spin systems. Such general bounds are not available for most bosoni…
