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…
Universal Dynamical Scaling of Strong-to-Weak Spontaneous Symmetry Breaking in Open Quantum Systems
Chang Shu, Kai Zhang, Zhu-Xi Luo +2
Strong-to-weak spontaneous symmetry breaking (SWSSB) defines a mixed-state phase of matter--without a pure-state counterpart--in which nonlinear observables such as the Rényi-2 cor…
Algebraic States in Continuum in Dimensional Non-Hermitian Systems
Ao Yang, Kai Zhang, Chen Fang
We report the existence of algebraically localized eigenstates embedded within the continuum spectrum of 2D non-Hermitian systems with a single impurity. These modes, which we term…
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…
Magnetochiral Charge Pumping due to Charge Trapping and Skin Effect in Chirality-Induced Spin Selectivity
Yufei Zhao, Kai Zhang, Jiewen Xiao +2
Chirality-induced spin selectivity (CISS) generates giant spin polarization in transport through chiral molecules, paving the way for novel spintronic devices and enantiomer separa…
Universal non-Hermitian skin effect in two and higher dimensions
Kai Zhang, Zhesen Yang, Chen Fang
Skin effect, experimentally discovered in one dimension, describes the physical phenomenon that on an open chain, an extensive number of eigenstates of a non-Hermitian hamiltonian…
