K-shell ionization cross sections of Chromium and Manganese have been calculated in the Binary Encounter Approximation and the results have been compared with theoretical cross sections of ECPSSR and the available experimental observations. Present results are found to be comparable to those of ECPSSR with a very less computational effort. Our cross sections show good agreement with experimental values.

We have developed an approach to calculate the full counting statistics of the Holstein polaron dot in a strong coupling regime. Using a polaron tunneling approximation we have derived an Levitov-Lesovik formula for the cumulant generating function with an effective normalized transmission coefficient. The effect of electron-phonon interactions on the charge transport through a contacted molecule was studied. We have simplified to contain a single electronic level linearly coupled to a local Holstein Phonon i.e. a bosonic oscillator degree of freedom with a single frequency. The vibrational modes of a such a quantum dot were also studied. We found the description of transport through molecules contacted using mechanically controlled break junctions.

In the present research paper, we have proposed a model for ratio of the radiation power & relativistic radiation power using the Stephen-Boltzmann-Schwarzschild-Hawking radiation formula to apply the variation of mass with velocity and calculated their values for different test black holes. We also have concluded that the relativistic radiation power decreases with the increase of velocity of the spinning black holes and becomes half of the radiation power due to non-relativistic effect, while the ratio of radiation power & relativistic radiation power (P/P rel ) increases with the increase of spinning velocity of the black holes.

I have calculated double ionization cross sections of silicon and phosphorus by electron impact using double binary encounter model. Hartree-Fock momentum distribution has been used for both the ejected electrons during collision process. Contributions from inner shell in the double ionization have been included in the calculations. The results obtained have been found in reasonably good agreement with the experimental observations.
