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…
Dynamically Induced Exceptional Phases in Quenched Interacting Semimetals
Carl Lehmann, Michael Schüler, Jan Carl Budich
We report on the dynamical formation of exceptional degeneracies in basic correlation functions of non-integrable one- and two-dimensional systems quenched to the vicinity of a cri…
