Quasi-bound states and late-time evolution of a massive fermion around a Reissner-Nordström black hole
Guang-Shang Chen, Cheng-Bo Yang, Shou-Shan Bao +2
A massive fermion around a charged black hole provides a gravitational analogue of atomic bound states and their relaxation. In this work, we study this system by formulating the r…
Subcritical bubble prehistory in weak first-order phase transition
Guangshang Chen, Yang Xiao, Jin Min Yang +1
Standard calculations of cosmological first-order phase transitions usually assume critical bubbles to nucleate on a homogeneous symmetric vacuum background. However, this assumpti…
Gravitational Wave Signature of Aspherical Bubbles Driven by Thermal Fluctuation
Ligong Bian, Guangshang Chen, Song Li +4
Cosmological first-order phase transitions are a well-motivated source of stochastic gravitational waves (GWs), but most predictions are made based on the highly idealized model of…
Revisiting the fermionic quasi-bound states around Schwarzschild black holes with improved analytic spectrum
Guang-Shang Chen, Cheng-Bo Yang, Shou-Shan Bao +2
Black holes have long served as a testing ground for probing theories of gravity and quantum mechanics. Notably, fundamental fields in the neighborhood of black holes exhibit rich…
