Nonequilibrium topological response under charge dephasing
Shuangyuan Lu, Lucas Q Silveira, Yizhi You
We explore nonequilibrium topological responses of symmetry-protected topological (SPT) states in open quantum systems subject to decoherence. For SPT wavefunctions protected by a…
Bilayer construction for mixed state phenomena with strong, weak symmetries and symmetry breakings
Shuangyuan Lu, Penghao Zhu, Yuan-Ming Lu
We introduce the bilayer construction, as a specific purification scheme for a general mixed state, where each mixed state has a one-to-one correspondence with a bilayer pure state…
Spacetime symmetry indicators for two-dimensional Floquet topological insulators
Shuangyuan Lu, Yuan-Ming Lu
Floquet Topological Insulators (FTIs) in two spatial dimensions can exhibit anomalous chiral edge modes despite a fully localized bulk, captured by a new topological invariant othe…
Exact Diagonalization Study on Avalanches in Many-Body Localized Constrained Spin Chains
Shuangyuan Lu
Avalanches are believed to be the mechanism behind the transition from many-body localization to the thermal phase. We utilize spin chains with constraints to study the physics of…
Optical and Raman selection rules for odd-parity clean superconductors
Shuangyuan Lu, Xu Yang, Yuan-Ming Lu
We derive selection rules in optical absorption and Raman scattering spectra, that can determine the parity of pairing order parameters under inversion symmetry in two classes of \…
Pairing Symmetry and Fermion Projective Symmetry Groups
Xu Yang, Shuangyuan Lu, Sayak Biswas +2
The Ginzburg-Landau (GL) theory is very successful in describing the pairing symmetry, a fundamental characterization of the broken symmetries in a paired superfluid or superconduc…
