On the mapping between bound states and black hole quasinormal modes via analytic continuation: a spectral instability perspective
Guan-Ru Li, Wei-Liang Qian, Xiao-Mei Kuang +5
In this work, we investigate the relation between bound states and quasinormal modes within black hole perturbation theory in the context of spectral instability. Our analysis indi…

Effective potential and scattering length of shielding polar molecules
Peng Xu, Gang Chen
We investigate the effective potential and scattering length of ultracold polar molecules under different shielding techniques. First, we derive the effective potential for two pol…

Precision measurement for open systems by non-hermitian linear response
Peng Xu, Gang Chen
The lower bound of estimated precision for a coherent parameter unitarily encoded in closed systems has been obtained, and such a lower bound is inversely proportional to the fluct…
