Gravitational wave echos from physical black holes
Yu-Song Cao, YanXia Liu, Ding-Fang Zeng
Gravitational wave echos from the coalescence of black hole binaries are often viewed as signals beyond general relativity or standard model. In this work, we show that these echos…

Propelling force from asymmetrically excited quantum vacuum with conventional mirrors
Yu-Song Cao, YanXia Liu, Ding-Fang Zeng
Investigations show that a time-varying mirror gives rise to asymmetrical vacuum radiation on its two sides, enabling one to extract propelling forces from the vacuum fluc…
