Algebraic Relaxation of Strong-to-Weak Symmetry-Breaking Order via Charge-Sector Broadening
Zi-Xi Fang, Kai Zhang
Strong-to-weak spontaneous symmetry breaking (SW-SSB) is a distinctive phenomenon of mixed quantum states, characterized by nonlinear long-range order associated with strong symmet…
Exceptional points and spectral cusps from density-wave fluctuation
Zixi Fang, Chen Fang
We report two types of singularities that arise from fluctuations during the formation of charge- or spin-density waves. The first is the exceptional point (EP), corresponding to a…
Double Majorana Vortex Flat Bands in the Topological Dirac Superconductor
Zhongyi Zhang, Zixi Fang, Shengshan Qin +3
Vortex lines, known as topological defects, are cable of trapping Majorana modes in superconducting topological materials. Previous studies have primarily focused on topological ba…
Tailoring Bound State Geometry in High-Dimensional Non-Hermitian Systems
Ao Yang, Zixi Fang, Kai Zhang +1
It is generally believed that the non-Hermitian effect (NHSE), due to its non-reciprocal nature, creates barriers for the appearance of impurity bound states. In this paper, we fin…
