A compellingly simple proof of the speed of sound for interacting bosons
J. Eisert
On physical grounds, one expects locally interacting quantum many-body systems to feature a finite group velocity. This intuition is rigorously underpinned by Lieb-Robinson bounds…

Lower bounds to variational problems with guarantees
J. Eisert
Variational methods play an important role in the study of quantum many-body problems, both in the flavor of classical variational principles based on tensor networks as well as of…
