Two distinct types of echoes in compact objects
Shui-Fa Shen, Kai Lin, Tao Zhu +3
In the black hole perturbation theory framework, two different physical pictures for echoes in compact objects have been proposed. The first mechanism interprets echoes as repeated…

Brownian thermal birefringent noise due to non-diagonal anisotropic photoelastic effect in multilayer coated mirrors
Yu-Pei Zhang, Shi-Xiang Yang, Wen-Hai Tan +3
Thermal noise in the mirror coatings limits the accuracy of today's most optical precision measurement experiments. Unlike the more commonly discussed thermal phase noise, the crys…
