Edge magnetism in transition metal dichalcogenide nanoribbons: Mean field theory and determinant quantum Monte Carlo
Francisco M. O. Brito, Linhu Li, João M. V. P. Lopes +1
Edge magnetism in zigzag transition metal dichalcogenide nanoribbons is studied using a three-band tight-binding model with local electron-electron interactions. Both mean field th…
Emergent Fermi surface in a many-body non-Hermitian Fermionic chain
Sen Mu, Ching Hua Lee, Linhu Li +1
Quantum degeneracy pressure (QDP) underscores the stability of matter and is arguably the most ubiquitous many-body effect. The associated Fermi surface (FS) has broad implications…
Broken-symmetry phases of interacting nested Weyl and Dirac loops
Miguel A. N. Araújo, Linhu Li
We study interaction-induced broken symmetry phases that can arise in metallic or semimetallic band structures with two nested Weyl or Dirac loops. The odered phases can be of the…
Dynamical topological invariant after a quantum quench
Chao Yang, Linhu Li, Shu Chen
We show how to define a dynamical topological invariant for general one-dimensional topological systems after a quantum quench. Focusing on two-band topological insulators, we demo…
-flux loop semimetals
Linhu Li, Stefano Chesi, Chuanhao Yin +1
We introduce a model of -flux loop semimetals which holds nodal loops described by a winding number . By adding some extra terms, this model can be transformed into a rece…
Topological invariants for phase transition points of one-dimensional topological systems
Linhu Li, Chao Yang, Shu Chen
We study topological properties of phase transition points of two topologically non-trivial classes (D and DIII) in one dimension by assigning a Berry phase defined…
Winding numbers of phase transition points for one-dimensional topological systems
Linhu Li, Chao Yang, Shu Chen
We study topological properties of phase transition points of one-dimensional topological quantum phase transitions by assigning winding numbers defined on closed circles around th…
Characterization of topological phase transitions via topological properties of transition points
Linhu Li, Shu Chen
We study topological properties of phase transition points of topological quantum phase transitions by assigning a topological invariant defined on a closed circle or surface surro…
Hidden-symmetry-protected topological phases on a one-dimensional lattice
Linhu Li, Shu Chen
We demonstrate the existence of topologically nontrivial phase in a one-dimensional fermionic lattice system subjected to synthetic gauge fields, which is beyond the standard Altla…
Topological insulator states in quasi-one-dimensional sawtooth chain
Zhihao Xu, Linhu Li
We report the discovery of flatten Bloch bands with nontrivial topological numbers in a quasi-one-dimensional sawtooth chain. We present the nearly flat-band with a obvious gap and…
