Non-thermal radiation of black hole off canonical typicality
We study the Hawking radiation of black holes by considering the canonical
typicality. For the universe consisting of black holes and their outer part, we
directly obtain a non-thermal radiation spectrum of an arbitrary black hole
from its entropy, which only depends on a few external qualities (known as
hairs), such as mass, charge, and angular momentum. Our result shows that the
spectrum of the non-thermal radiation is independent of the detailed quantum
tunneling dynamics across black hole horizon. We prove that the black hole
information paradox is naturally resolved by taking account the correlation
between black hole and its radiation in our approach.Comment: 5 pages, 1 figure, pulished on Europhysics Letters, comments are

Time-reversal of multiple-force-point chordal
Chordal SLE is a natural variant of chordal SLE
curve. It is a family of random non-crossing curves on the upper half plane
from 0 to , whose law is influenced by additional force points on
. When there are force points away from the origin, the law of
SLE is not reversible as the ordinary chordal
SLE. Zhan (2019) give an explicit description of the law of the time
reversal of SLE when all force points lies on the
same sides of the origin, and conjectured that a similar result holds in
general. In this paper we prove his conjecture. In particular, based on Zhan's
result, using the techniques from the Imaginary Geometry developed by Miller
and Sheffield (2013), we show that when , the law of the time
reversal of non-boundary filling
process is absolutely continuous with respect to
for some
determined by , with the Radon-Nikodym derivative being a
product of conformal derivatives.Comment: 13 pages, 6 figure
