A Solvable Model for Discrete Time Crystal Enforced by Nonsymmorphic Dynamical Symmetry
Zi-Ang Hu, Bo Fu, Xiao Li +1
Discrete time crystal is a class of nonequilibrium quantum systems exhibiting subharmonic responses to external periodic driving. Here we propose a class of discrete time crystals…
Half-Quantized Hall Effect at the Parity-Invariant Fermi Surface
Jin-Yu Zou, Rui Chen, Bo Fu +3
Condensed matter realization of a single Dirac cone of fermions in two dimensions is a long-standing issue. Here we report the discovery of a single gapless Dirac cone of half-quan…
Signature of parity anomaly in the measurement of optical Hall conductivity in quantum anomalous Hall systems
Zi-Ang Hu, Huan-Wen Wang, Bo Fu +2
Parity anomaly is a quantum mechanical effect that the parity symmetry in a two-dimensional classical action is failed to be restored in any regularization of the full quantum theo…

We investigate disorder-driven topological phase transitions in quantized electric quadrupole insulators. We show that chiral symmetry can protect the quantization of the quadrupol…
Equivalence of Coefficients Extraction of One-loop Master Integrals
Yang An, Zi-ang Hu, Zhongjie Huang +2
Now there are many different methods to do the PV-reduction for the one loop amplitudes. Two of them are unitarity cut method and generalized unitarity cut method. In this short pa…
