Exceptional Non-Hermitian Phases in Disordered Quantum Wires
Benjamin Michen, Tommaso Micallo, Jan Carl Budich
We demonstrate the occurrence of nodal non-Hermitian (NH) phases featuring exceptional degeneracies in chiral-symmetric disordered quantum wires, where NH physics naturally arises…

Topological entanglement properties of disconnected partitions in the Su-Schrieffer-Heeger model
Tommaso Micallo, Vittorio Vitale, Marcello Dalmonte +1
We study the disconnected entanglement entropy, , of the Su-Schrieffer-Heeger model. is a combination of both connected and disconnected bipartite entanglement entropies…
