Non-Hermitian skin effect and chiral damping in open quantum systems
Fei Song, Shunyu Yao, Zhong Wang
One of the unique features of non-Hermitian Hamiltonians is the non-Hermitian skin effect, namely that the eigenstates are exponentially localized at the boundary of the system. Fo…
Non-Hermitian Chern bands
Shunyu Yao, Fei Song, Zhong Wang
The relation between chiral edge modes and bulk Chern numbers of quantum Hall insulators is a paradigmatic example of bulk-boundary correspondence. We show that the chiral edge mod…
Topological invariants of Floquet systems: General formulation, special properties, and Floquet topological defects
Shunyu Yao, Zhongbo Yan, Zhong Wang
Periodically driven (Floquet) systems have been under active theoretical and experimental investigations. This paper aims at a systematic study in the following aspects of Floquet…
Floquet multi-Weyl points in crossing-nodal-line semimetals
Zhongbo Yan, Zhong Wang
Weyl points with monopole charge have been extensively studied, however, real materials of multi-Weyl points, whose monopole charges are higher than , have yet to be fou…
Nodal-knot semimetals
Ren Bi, Zhongbo Yan, Ling Lu +1
Topological nodal-line semimetals are characterized by one-dimensional lines of band crossing in the Brillouin zone. In contrast to nodal points, nodal lines can be in topologicall…
Tunable Weyl Points in Periodically Driven Nodal Line Semimetals
Zhongbo Yan, Zhong Wang
Weyl semimetals and nodal line semimetals are characterized by linear band touching at zero-dimensional points and one-dimensional lines, respectively. We predict that a circularly…
Collective modes in nodal line semimetals
Zhongbo Yan, Peng-Wei Huang, Zhong Wang
Recently, the nodal line semimetals have attracted considerable interests in condensed matter physics. We show that their distinct band structure can be detected by measuring the c…
Fractionalized Metals and Superconductors in Three Dimensions
Zhong Wang
We study three-dimensional metals with nontrivial correlation functions and fractionalized excitations. We formulate for such states a gauge theory, which also naturally describes…
Simplified topological invariants for interacting insulators
Zhong Wang, Shou-Cheng Zhang
We propose general topological order parameters for interacting insulators in terms of the Green's function at zero frequency. They provide an unified description of various intera…
