Many-body quantum sign structures as non-glassy Ising models
Tom Westerhout, Mikhail I. Katsnelson, Andrey A. Bagrov
The non-trivial phase structure of the eigenstates of many-body quantum systems severely limits the applicability of quantum Monte Carlo, variational, and machine learning methods.…

The role of correlated hopping in many-body physics of flat-band systems: Nagaoka ferromagnetism
Tom Westerhout, Mikhail I. Katsnelson
In narrow-band systems, correlated contribution to effective hopping becomes important, and one needs to carefully consider three types of hopping processes: between doubly and sin…
