Dynamical zero modes, boundary dependence, and numerical instability in dynamical quantum phase transitions

Siyan Lin, Xu Feng, Xiuhua Tian +1

Boundary conditions are usually expected to cause only finite-size corrections to bulk quantities, but this expectation can fail for dynamical quantum phase transitions. In this wo…

Superradiant phase transition in cavity magnonics via Floquet engineering

Si-Yan Lin, Fei Gao, Ye-Jun Xu +4

We propose a scheme to engineer the superradiant phase transition (SPT) in cavity magnonics by periodically modulating the frequency of the magnon mode. The studied system is compo…

Distribution of fidelity zeros in two-band topological models

Siyan Lin, Zhen-Yu Zheng, Shu Chen

We investigate the distribution of fidelity zeros in two-band topological models by extending the phase transition driving parameter into the complex plane. Within the biorthogonal…

Nonreciprocal superradiant quantum phase transition induced by the magnon Kerr effect

Guo-Qiang Zhang, Si-Yan Lin, Wei Feng +3

Recently, proposals for realizing a nonreciprocal superradiant quantum phase transition (SQPT) have been put forward, based on either nonreciprocal interactions between two spin en…

Loschmidt echo zeros in finite-size quantum systems with linear quench

Zhen-Yu Zheng, Xudong Liu, Siyan Lin +2

Dynamical quantum phase transitions reveal singularities in quench dynamics, characterized by the emergence of Loschmidt echo zeros at critical times, which usually exist only in t…

Third-order exceptional surface in a pseudo-Hermitian superconducting circuit

Guo-Qiang Zhang, Si-Yan Lin, Wei Feng +3

Compared with an isolated exceptional point, exceptional surfaces in non-Hermitian systems are more robust against environment noises, fabrication errors, and experimental uncertai…

Deflection and gravitational lensing with finite distance effect in the strong deflection limit in stationary and axisymmetric spacetimes

Yujie Duan, Siyan Lin, Junji Jia

We study the deflection and gravitational lensing (GL) of both timelike and null signals in the equatorial plane of arbitrary stationary and axisymmetric spacetimes in the strong d…
