Analytical theory of cat scars with discrete time crystalline dynamics in Floquet systems
Biao Huang
We reconstruct the spectral pairing (SP) theories to enable analytical descriptions of eigenstate spatiotemporal orders in translation-invariant systems without prethermal conditio…
Discrete time crystals enforced by Floquet-Bloch scars
Biao Huang, Tsz-Him Leung, Dan Stamper-Kurn +1
We analytically identify a new class of quantum scars protected by spatiotemporal translation symmetries, dubbed Floquet-Bloch scars. They distinguish from previous (quasi-)static…
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…
Clean Floquet Time Crystals: Models and Realizations in Cold Atoms
Biao Huang, Ying-Hai Wu, W. Vincent Liu
Time crystals, a phase showing spontaneous breaking of time-translation symmetry, has been an intriguing subject for systems far away from equilibrium. Recent experiments found suc…
Interplay of non-symmorphic symmetry and spin-orbit coupling in hyperkagome spin liquids: Applications to NaIrO
Biao Huang, Yong Baek Kim, Yuan-Ming Lu
NaIrO provides a material platform to study three-dimensional quantum spin liquids in the geometrically frustrated hyperkagome lattice of Ir ions. In this work,…
Spinor Condensates on a Cylindrical Surface in Synthetic Gauge Fields
Tin-Lun Ho, Biao Huang
We point out that by modifying the setup of a recent experiment that generates a Dirac string, one can create a quasi 2D spinor Bose condensate on a cylindrical surface with a synt…
Hall Viscosity Revealed via Density Response
Biao Huang
Quantum Hall systems are recently shown to possess a quantity sensitive to the spatial geometry and topology of the system, dubbed the Hall viscosity . Despite the extensive t…
The Local Spin Structure of Large Spin Fermions
Tin-Lun Ho, Biao Huang
We show that large spin fermions have very rich spin structures. The local spin order of a spin- Fermi gas is a linear combination of (particle-hole) angular momentum state…
Five-dimensional metric gravity and the accelerated universe
Biao Huang, Song Li, Yongge Ma
The metric theories of gravity are generalized to five-dimensional spacetimes. By assuming a hypersurface-orthogonal Killing vector field representing the compact fifth dime…
