Parity-symmetry-breaking quantum phase transition via parametric drive in a cavity magnonic system
Guo-Qiang Zhang, Zhen Chen, Wei Xiong +2
We study the parity-symmetry-breaking quantum phase transition (QPT) in a cavity magnonic system driven by a parametric field, where the magnons in a ferrimagnetic yttrium-iron-gar…

Exceptional Point and Cross-Relaxation Effect in a Hybrid Quantum System
Guo-Qiang Zhang, Zhen Chen, Da Xu +7
Exceptional points (EPs) are exotic degeneracies of non-Hermitian systems, where the eigenvalues and the corresponding eigenvectors simultaneously coalesce in parameter space, and…
