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…

Thermal Area Law for Lattice Bosons
Marius Lemm, Oliver Siebert
A physical system is said to satisfy a thermal area law if the mutual information between two adjacent regions in the Gibbs state is controlled by the area of their boundary. Therm…

The spin-one Motzkin chain is gapped for any area weight
Radu Andrei, Marius Lemm, Ramis Movassagh
We consider the spin-one Motzkin chain with area weight . We resolve three questions from the literature about this model. We prove (i) existence of a uniform spectral gap for…
