Probing Unruh Effect from Enhanced Decoherence
Ran Li, Zhong-Xiao Man, Jin Wang
We investigate the decoherence of an Unruh-DeWitt detector coupled to scalar, electromagnetic, and spinor fields in four-dimensional Minkowski spacetime. By employing the Schwinger…

Impacts of wormholes on false vacuum bubble tunneling
Hong Wang, Yuxuan Wu, Ran Li +1
In this study, we generalize the work of Farhi, Guth and Guven [Nucl. Phys. B 339 (1990) 417] to include a wormhole effect. We study the influence of the wormhole on the tunneling…

Critical slowing down of black hole phase transition and kinetic crossover in supercritical regime
Ran Li, Kun Zhang, Jiayue Yang +2
Reissner-Nordström-Anti-de Sitter (RNAdS) black holes in the extended phase space exhibit critical behavior analogous to the liquid-gas system, with critical exponents matching th…
