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…
Direct dynamical characterization of higher-order topological insulators with nested band inversion surfaces
Linhu Li, Weiwei Zhu, Jiangbin Gong
Higher-order topological insulators (HOTIs) are systems with topologically protected in-gap boundary states localized at their -dimensional boundaries, with the system d…
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…
Topological characterization of non-Hermitian multiband systems using Majorana's Stellar Representation
Wei Xin Teo, Linhu Li, Xizheng Zhang +1
For topological characterization of non-Hermitian multiband systems, Majorana's stellar representation (MSR) is applied to 1D multiband models consisting of asymmetric nearest-neig…
