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…
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-…
Astrophysical Configurations with Background Cosmology: Probing Dark Energy at Astrophysical Scales
Andres Balaguera-Antolinez, David F. Mota, Marek Nowakowski
We explore the effects of a positive cosmological constant on astrophysical and cosmological configurations described by a polytropic equation of state. We derive the conditions fo…
Long Range Forces from Quantum Field Theory at Zero and Finite Temperature
Marek Nowakowski
We discuss the derivation of Newtonian potentials in the framework of quantum field theory. We focus on two particular points: on long range forces i.e. forces which fall off as $1…
