In fact, in a wide variety of cases of two-dimensional toy models, there has been much attention to the backreaction issue that exhibits black hole formation and evaporation [11{23]. In particular, the black hole temperature characterizing Hawking radiation plays an im- Hawking radiation is theoretical black body radiation that is theorized to be released outside a black hole's event horizon because of relativistic quantum effects. It is named after the physicist Stephen Hawking, who developed a theoretical argument for its existence in 1974. Hawking radiation is a purely … See more Black holes are astrophysical objects of interest primarily because of their compact size and immense gravitational attraction. They were first predicted by Einstein's 1915 theory of general relativity, before astrophysical … See more Hawking radiation is dependent on the Unruh effect and the equivalence principle applied to black-hole horizons.
