because of production process and constrains conditions, circular graphene sheet may be opposed to structural defect and pin hole, respectively. some of the defects and pin hole on a circular graphene sheet can be considered as an eccentric hole on the sheet. hence, analyzing behavior of circular graphene sheet with an eccentric hole is important. free vibration of an eccentric annular graphene...

Electronic coupling V(da) is one of the key parameters that determine the rate of charge transfer through DNA. While there have been several computational studies of V(da) for hole transfer, estimates of electronic couplings for excess electron transfer (ET) in DNA remain unavailable. In the paper, an efficient strategy is established for calculating the ET matrix elements between base pairs in...

We consider the decay of a particle with some energy $E_{0}>0$ inside ergosphere black hole. After first one particles $E_{1}<0$ falls towards hole while second $% E_{2}>E_{0}\,\ $moves in outward direction. It bounces back from reflecting shell and, afterwards, process repeats. For radial motion charged Reissner-Nordst\"{o}m metric, result depends strongly on concrete scenario. In particular, ...

The life-times due to Auger-electron emission for a hole on a deep electronic shell of neutral and charged sodium clusters are studied for different sizes. We consider spherical clusters and calculate the Auger-transition probabilities using the energy levels and wave functions calculated in the LocalDensity-Approximation (LDA). We obtain that Auger emission processes are energetically not allo...

We investigate the non-linear interaction of a strong Gravitational Wave with the plasma during the collapse of a massive magnetized star to form a black hole, or during the merging of neutron star binaries (central engine). We found that under certain conditions this coupling may result in an efficient energy space diffusion of particles. We suggest that the atmosphere created around the centr...

We investigate the nonlinear interaction of a strong gravitational wave with the plasma during the collapse of a massive magnetized star and subsequent formation of a black hole or during the merging of neutron star binaries (the central engine). We found that under certain conditions this coupling may result in an efficient energy-space diffusion of particles. We suggest that the atmosphere cr...

The bandgap narrowing (BGN) in zincblende III–V semiconductors is calculated a finite-temperature full Random-Phase Approximation (RPA) formalism based on an isotropic dispersion model. cases of n-type and p-type quasi-neutral regions the case neutral electron–hole plasma are elaborated for technologically important materials GaAs, AlAs, InAs, GaP, InP, GaSb, InSb, zb-GaN, zb-InN, Al0.3Ga0.7As ...

In this article, we analytically investigate the microstructure of a five-dimensional neutral Gauss–Bonnet black hole, in background anti-de Sitter spacetime, by using scalar curvature Ruppeiner geometry constructed via adiabatic compressibility. The details associated with small-large hole phase transition are probed parameter space pressure and volume. shows similar properties for both phases...
