A Toy Model for Black Hole in Noncommutative Spaces
M. Demetrian, P. Presnajder
We present a new point of view on the problem of the Schwarzschild black hole in the noncommutative spaces, proposed recently by F. Nasseri. We apply our treatment also to the case…
Motion of a testing particle in gravitational field of a ring
Michal Demetrian
The planar motion of a testing body in the field of gravity of the massive ring is studied. The "perihelion" precession due to non-relativistic reasons is demonstrated on this simp…
Approximation of the energy levels of the particle on a segment by energy levels of the particle in monomial potential well
Michal Demetrian
This simple text considers an application of Bohr-Sommerfeld quantization rule. It might be of interest for the students of physics.
Particle in a box at high temperature
Michal Demetrian
High temperature expansion of the partition function for a particle on a segment of a line is found to show an example of the quantum system that thermodynamical functions do not a…
A Note on Derivation of Rutherford Formula within Born Approximation
Michal Demetrian
It is shown in this paper that one does not need to use just exponential dumping factor when computing the Rutherford formula within Born approximation. Text, which is very simple,…
How to Introduce A World Time to A Part of Two Dimensional de Sitter Manifold
Michal Demetrian
We define 1+1 dimensional de Sitter manifold in this paper and we consider various coordinate systems on it. Some interesting aspects of the general theory of relativity are demons…
