Exact solution of single impurity problem in non-reciprocal lattices: impurity induced size-dependent non-Hermitian skin effect
Yanxia Liu, Yumeng Zeng, Linhu Li +1
Non-Hermitian non-reciprocal systems are known to be extremely sensitive to boundary conditions, exhibiting diverse localizing behaviors and spectrum structures when translational…
Delocalization of topological edge states
Weiwei Zhu, Wei Xin Teo, Linhu Li +1
The non-Hermitian skin effect (NHSE) in non-Hermitian lattice systems depicts the exponential localization of eigenstates at system's boundaries. It has led to a number of counter-…
Quantized classical response from spectral winding topology
Linhu Li, Sen Mu, Ching Hua Lee +1
Topologically quantized response is one of the focal points of contemporary condensed matter physics. While it directly results in quantized response coefficients in quantum system…
Point-gap topology with complete bulk-boundary correspondence in dissipative quantum systems
Jian-Song Pan, Linhu Li, Jiangbin Gong
The spectral and dynamical properties of dissipative quantum systems, as modeled by a damped oscillator in the Fock space, are investigated from a topological point of view. Unlike…
Impurity induced scale-free localization
Linhu Li, Ching Hua Lee, Jiangbin Gong
This work develops a full framework for non-Hermitian impurity physics in a non-reciprocal lattice, with PBCs, OBCs and even their interpolations being special cases across a whole…
Critical non-Hermitian Skin Effect
Linhu Li, Ching Hua Lee, Sen Mu +1
This work uncovers a new class of criticality where eigenenergies and eigenstates of non-Hermitian lattice systems jump discontinuously across a critical point in the thermodynamic…
