Complex Frequency Fingerprint: Interacting Driven Non-Hermitian Skin Effect
Zhesen Yang, Zihan Wang, Juntao Huang +2
The excitation properties of quantum many-body systems are encoded in their response functions. These functions define an associated response Hamiltonian, which is intrinsically no…
Anomalous Scaling Behaviors of the Green's Function in Critical Skin Effects
Yifei Yi, Zhesen Yang
We study the Green's functions in non-Hermitian systems exhibiting the critical non-Hermitian skin effect (critical NHSE) using a double-chain Hatano-Nelson model with inter-chain…
Exceptional deficiency of non-Hermitian systems
Zhen Li, Xulong Wang, Rundong Cai +5
Exceptional points (EPs) are non-Hermitian singularities associated with the coalescence of individual eigenvectors accompanied by the degeneracy of their complex energies. Here, w…
Complex Frequency Detection in a Subsystem
Juntao Huang, Jiangping Hu, Zhesen Yang
In this study, we systematically explore the non-Hermitian skin effect (NHSE) and its associated complex-frequency detection in the context of a frequency-dependent non-Hermitian H…
Complex Frequency Fingerprint: Basic Concept and Theory
Juntao Huang, Kun Ding, Jiangping Hu +1
We introduce the complex frequency fingerprint (CFF), an experimentally accessible method for detecting the complex frequency Green's function (GF). Unlike the real frequency GF, w…
An Explicit Wavefunction of the Interacting Non-Hermitian Spin-1/2 1D System
Yue Wang, Xiangyu Zhang, Zhesen Yang +1
We present an explicit Bethe-ansatz wavefunction to a 1D spin- interacting fermion system, manifesting a many-body resonance resulting from the interplay between inter…
