... the mass distribution of BHs has been considered by Postnov and Cherepashchuk (2003). Deficit of low-mass BH and the gap in the range (2 – 4) M may be due to enhanced quantum evaporation of BH which have been suggested in some multidimensional models of gravity (e.g. Randall and Sundrom, 1999). In ...

... Such persistent magnetic ordering cannot be explained by magnetic forces, which are typically much smaller than kT . They can actually be ignored; to understand this we must turn to the much larger electrostatic interactions (Problem 13.2), and quantum mechanics. Let’s start with the simplest possib ...
