Many-electron characterizations of higher-charge superconductors
Zi-Hao Dong, Yi Zhang
The theoretical understanding of conventional superconductivity as the phonon-assisted formation and condensation of two-electron Cooper pairs is a significant triumph in condensed…

1D Spontaneous Symmetry Breaking in thermal equilibrium via Non-Hermitian Construction
Jia-Bao Wang, Zi-Hao Dong, Yi Zhang
Spontaneous symmetry breaking generally circumvents one-dimensional systems with local interactions in thermal equilibrium. Here, we analyze a category of one-dimensional Hermitian…

Enhanced nonlinear Hall effect by Cooper pairs near superconductor criticality
Zi-Hao Dong, Hui Yang, Yi Zhang
Unlike the linear Hall effect that requires broken time-reversal symmetry, the nonlinear Hall effect may occur in time-reversal symmetric systems as long as there exists a non-zero…
