Milestones,nd Frank on the “anomalous” Doppler effect. It is impossible to summarize all the important work in the field in this work, but we think it is both useful and pedagogical to have a chronogram of some of the most relevant milestones.不可救药 发表于 2025-3-25 16:20:17
Superradiance in Flat Spacetime,–165, 1929), who pioneered studies of Dirac’s equation in the presence of a step potential. He showed that an electron beam propagating in a region with a large enough potential barrier . can emerge without the exponential damping expected from nonrelativistic quantum tunneling processes.

Superradiance in Black-Hole Physics,e cooling, etc. All these forms of dissipation are associated with some medium or some matter field that provides the . for superradiance. It is thus truly remarkable that—when spacetime is .—superradiance can also occur in vacuum, even at the classical level. In this section we discuss in detail .,Expand 发表于 2025-3-26 00:17:03
