Floquet chiral hinge modes and their interplay with Weyl physics in a three-dimensional lattice
Biao Huang, Viktor Novičenko, André Eckardt +1
We demonstrate that a three dimensional time-periodically driven (Floquet) lattice can exhibit chiral hinge states and describe their interplay with Weyl physics. A peculiar type o…
Moire Localization in Two Dimensional Quasi-Periodic Systems
Biao Huang, W. Vincent Liu
We discuss a two-dimensional system under the perturbation of a Moire potential, which takes the same geometry and lattice constant as the underlying lattices but mismatches up to…
Dynamical Singularities of Floquet Higher-Order Topological Insulators
Haiping Hu, Biao Huang, Erhai Zhao +1
We propose a versatile framework to dynamically generate Floquet higher-order topological insulators by multi-step driving of topologically trivial Hamiltonians. Two analytically s…
Floquet Higher-Order Topological Insulators with Anomalous Dynamical Polarization
Biao Huang, W. Vincent Liu
Higher order topological insulators (HOTI) have emerged as a new class of phases, whose robust in-gap "corner" modes arise from the bulk higher-order multipoles beyond the dipoles…
Field induced quantum spin liquid with spinon Fermi surfaces in the Kitaev model
Hong-Chen Jiang, Chang-Yan Wang, Biao Huang +1
Recent experimental evidence for a field-induced quantum spin liquid (QSL) in -RuCl calls for an understanding for the ground state of honeycomb Kitaev model under a magneti…
Classification and properties of quantum spin liquids on the hyperhoneycomb lattice
Biao Huang, Wonjune Choi, Yong Baek Kim +1
The family of "Kitaev materials" provides an ideal platform to study quantum spin liquids and their neighboring magnetic orders. Motivated by the possibility of a quantum spin liqu…
