Hybrid higher-order skin-topological modes in non-reciprocal systems
Ching Hua Lee, Linhu Li, Jiangbin Gong
Higher-order phases are characterized by corner or hinge modes that arise due to the interesting interplay of localization mechanisms along two or more dimensions. In this work, we…
Direct prediction of corner state configurations from edge winding numbers in 2D and 3D chiral-symmetric lattice systems
Linhu Li, Muhammad Umer, Jiangbin Gong
Higher-order topological phases feature topologically protected boundary states in lower dimensions. Specifically, the zero-dimensional corner states are protected by the th-ord…
Robust one-dimensionality at twin-grain-boundaries in MoSe
Tilen Cadez, Linhu Li, Eduardo V. Castro +1
We show that 1D electron states confined at twin-grain-boundaries in MoSe can be modeled by a three-orbital tight binding model including a minimum set of phenomenological ho…
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…
Realistic Floquet semimetal with exotic topological linkages between arbitrarily many nodal loops
Linhu Li, Ching Hua Lee, Jiangbin Gong
Valence and conduction bands in nodal loop semimetals (NLSMs) touch along closed loops in momentum space. If such loops can proliferate and link intricately, NLSMs become exotic to…
Geometrical meaning of winding number and its characterization of topological phases in one-dimensional chiral non-Hermitian systems
Chuanhao Yin, Hui Jiang, Linhu Li +2
We unveil the geometrical meaning of winding number and utilize it to characterize the topological phases in one-dimensional chiral non-Hermitian systems. While chiral symmetry ens…
