Berry curvature inside parity-time-symmetry protected exceptional surface
P. Wang, L. Jin, Z. Song
A three-dimensional non-Hermitian Hamiltonian with parity-time symmetry can exhibit a closed exceptional surface (EP surface) in momentum space, which is a non-Hermitian deformatio…
Qualitative quantum simulation of resonant tunneling and localization with the shallow quantum circuits
J. L. Shen, P. Wang
In a circuit-based quantum computer, the computing is performed via the discrete-time evolution driven by quantum gates. Accurate simulation of continuoustime evolution requires a…
Transition from degeneracy to coalescence: theorem and applications
P. Wang, K. L. Zhang, Z. Song
Exceptional point (EP) is exclusive for non-Hermitian system and distinct from that at a degeneracy point (DP), supporting intriguing dynamics, which can be utilized to probe quant…
Moiré pattern of spin liquid and Neel magnet in a Kitaev chain
R. Wang, P. Wang, K. L. Zhang +1
A moiré pattern occurs when two periodic structures in a system have a slight mismatch period, resulting the coexistence of distinct phases in different large-scale spacial regions…
Semi-localization transition driven by a single asymmetrical tunneling
P. Wang, K. L. Zhang, Z. Song
A local impurity usually only strongly affects few single-particle energy levels, thus cannot induce a quantum phase transition (QPT), or any macroscopic quantum phenomena in a man…
Non-Hermitian phase transition and eigenstate localization induced by asymmetric coupling
P. Wang, L. Jin, Z. Song
We investigate a uniformly coupled non-Hermitian system with asymmetric coupling amplitude. The asymmetric coupling equals to a symmetric coupling threaded by an imaginary gauge fi…
