Electron dichotomy on theSrTiO3defect surface augmented by many-body effects

Radiative heat transfer: many-body effects

Heat transfer by electromagnetic radiation is one of the common methods of energy transfer between objects. Using the fluctuation-dissipation theorem, we have studied the effect of particle arrangement in the transmission of radiative heat in many-body systems. In order to show the effect of the structure morphology on the collective properties, the radiative heat transfer is studied and the re...

Many-body effects in Auger electron emission from Graphene

Many-body Perturbation Study of Electron Correlation Effects on Nmr Parameters*

NMR is routinely used as an indispensable research tool in present-day chemical laboratories because a wide variety of parameters can be extracted from the response of an ensemble of nuclear spins to a resonant excitation. Among them, the chemical shift in nuclear magnetic shielding and the electroncoupled nuclear spin-spin coupling are direct measures of the change in chemical environment arou...

Effects of many-electron atom polarization in electron-hole formalism

As is known [1], for odd number of electrons the Hartree Fock method of self-consistent field gives the equation, calculation with which help is connected to a problem of diagonalizing a matrix Lagrange multiplier. It results to possible noncommutativity of a Fock operator with the operator density matrix (a projector on subspace of orbitals for electron in a atomic core) and, hence, to absence...

Nonextensive Statistical Effects on Nuclear Astrophysics and Many-body Problems

Density and temperature conditions in many stellar core (like the solar core) imply the presence of nonideal plasma effects with memory and long-range interactions between particles. This aspect suggests the possibility that the stellar core could not be in a global thermodynamical equilibrium but satisfies the conditions of a metastable state with a stationary (nonextensive) power law distribu...
