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…

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…

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…
