Quantum entanglement and non-Hermiticity in free-fermion systems

LM Chen, Y Zhou, SA Chen, P Ye - Chinese Physics Letters, 2024 - iopscience.iop.org
This topical review article reports rapid progress on the generalization and application of
entanglement in non-Hermitian free-fermion quantum systems. We begin by examining the …

Evolution of dynamical signature in the X-cube fracton topological order

C Zhou, MY Li, Z Yan, P Ye, ZY Meng - Physical Review Research, 2022 - APS
As an unconventional realization of topological orders with an exotic interplay of topology
and geometry, fracton (topological) orders feature subextensive topological ground-state …

Fractons, non-Riemannian geometry, and double field theory

S Angus, M Kim, JH Park - Physical Review Research, 2022 - APS
We initiate a systematic study of fracton physics within the geometric framework of double
field theory. We ascribe the immobility and large degeneracy of the former to the non …

Fractionalizing global symmetry on looplike topological excitations

SQ Ning, ZX Liu, P Ye - Physical Review B, 2022 - APS
Symmetry fractionalization on topological excitations is one of the most remarkable quantum
phenomena in topological orders with symmetry, ie, symmetry-enriched topological phases …
