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…
Topological Mechanics of Entangled Networks
Juntao Huang, Jiabin Liu, Shaoting Lin
Entangled networks are ubiquitous in tissues, polymers, and fabrics. However, their mechanics remain insufficiently understood due to the complexity of the topological constraints…
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…
