Nodal Spectral Functions Stabilized by Non-Hermitian Topology of Quasiparticles
Carl Lehmann, Tommaso Micallo, Jan Carl Budich
In quantum materials, basic observables such as spectral functions and susceptibilities are determined by Green's functions and their complex quasiparticle spectrum rather than by…
Correlation-Induced Sensitivity and Non-Hermitian Skin Effect of Quasiparticles
Tommaso Micallo, Carl Lehmann, Jan Carl Budich
Non-Hermitian (NH) Hamiltonians have been shown to exhibit unique signatures, including the NH skin effect and an exponential spectral sensitivity with respect to boundary conditio…
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…
