Can neural quantum states learn volume-law ground states?
Giacomo Passetti, Damian Hofmann, Pit Neitemeier +3
We study whether neural quantum states based on multi-layer feed-forward networks can find ground states which exhibit volume-law entanglement entropy. As a testbed, we employ the…

Functional renormalization group for non-Hermitian and -symmetric systems
Lukas Grunwald, Volker Meden, Dante M. Kennes
We generalize the vertex expansion approach of the functional renormalization group to non-Hermitian systems. As certain anomalous expectation values might not vanish, additional t…
