Stationary Dirac condensates around Kerr black holes
Sen Guo, Peng-Yu Chen, Yi-Han Huang +4
Ultralight bosonic fields can form macroscopic clouds around rotating black holes, whereas the existence of analogous stationary fermionic condensates is strictly constrained by th…

Superradiant Bose--Einstein condensates around Kerr black holes
Sen Guo, Lin Wen, Xiao-Xiong Zeng
Ultralight bosonic dark matter can accumulate around a rotating black hole, where superradiance amplifies the field until a macroscopic cloud forms. Whether such a cloud behaves as…
