Extracting Information from the Gravitational Redshift of Compact Rotating Objects
Paul Nunez, Marek Nowakowski
When rotation is not taken into account, the measurement of the Gravitational Redshift can provide unique information about the compactness () of the star. Rotation alters the…
Comparing two approaches to Hawking radiation of Schwarzschild-de Sitter black holes
I. Arraut, D. Batic, M. Nowakowski
We study two different ways to analyze the Hawking evaporation of a Schwarzschild-de Sitter black hole. The first one uses the standard approach of surface gravity evaluated at the…
The fate of a gravitational wave in de Sitter spacetime
M. Nowakowski, I. Arraut
If we want to explain the recently discovered accelerated stage of the universe, one of the option we have is to modify the Einstein tensor. The simplest such modification, in agre…
Long Tail of Quantum Decay from Scattering Data
M. Nowakowski, N. G. Kelkar
Whereas the short time behaviour of an unstable quantum mechanical system is well understood from its theoretical as well as experimental side, the long time tail of the very same…
Quantum time scales in alpha tunneling
N. G. Kelkar, H. M. Castaneda, M. Nowakowski
The theoretical treatment of alpha decay by Gamow is revisited by investigating the quantum time scales in tunneling. The time spent by an alpha particle in front of the barrier an…
On the bound states of the Dirac equation in the extreme Kerr metric
Davide Batic, Marek Nowakowski
We study the eigenvalues of the angular equation arising after the separation of the Dirac equation in the extreme Kerr metric. To this purpose a self-adjoint holomorphic operator…
Analysis of averaged multichannel delay times
N. G. Kelkar, M. Nowakowski
The physical significances and the pros and cons involved in the usage of different time delay formalisms are discussed. The delay time matrix introduced by Eisenbud, where only s-…
