UNIFORMLY ACCELERATED MOTION and THOMAS PRECESSION in DSR:
Predictions
of Quantum Gravity effects
|
Abstract: |
In this work, we have studied two relativistic phenomenons - the
uniformly accelerated motion and the Thomas precession - and calculated how
they were modified by several approaches of Deformed Special Relativity
(DSR).
We used Magueijo-Smolin and Snyder deformations. We obtained some
pertubative
corrections to the two phenomenons, and in one case, we obtained that a
uniformly accelerated observer could reach the speed of light in a finite
duration, which depends of his mass.

Abstract: |
We proposed that a discretized torus can be suitable candidate for the very
early universe and we show when the number of finit sets approches the
planck density the corelation would be complicated.It seems this idead
might be solved horizon problem.Finally we speculate on binding energy
in the very early universe by using cluster expansion methode.This idea
might be solved singularity problem.

Quantum cosmology with scalar field |
Abstract: |
The Wheeler-DeWitt equation of standart cosmological models
with a
scalar field is formulated with arbitrary factor ordering. Exact solutions
for
arbitrary factor ordering are presented. These solutions are permited by
factor
ordering parameters. Moreover, relevance of continuity equation derived from
the Wheeler-DeWitt equation is depending on these parameters. Consequently
parameters family is reduced.

Universal area spectrum in single-horizon black holes
|
Abstract: |
We investigate highly damped quasinormal mode of single-horizon
black holes motivated by its relation to loop quantum gravity.
Using the WKB approximation, we show that the real part of the frequency
approaches the value $T_{\rm H}\ln 3$ for dilatonic black hole.
It is surprising since the area specrtum of the black hole determined by the
Bohr's
correspondence principle completely agrees with that of
Schwarzschild black hole for any values of
the electromagnetic charge or the dilaton coupling.
We discuss its generality for single-horizon black holes and the meaning
in loop quantum gravity.
