The GWapproximation to the formally exact many-body perturbation
theory has been applied successfully to materials for several decades. Since the
practical calculations are extremely cumbersome, the . . . . .
This paper summarizes the present views on construction of the electron quantum transport equations based on the
Non-Equilibrium Green’s Functions approach. The basic tool is the so-called Ansatz dec . . . . .
Econophysics is a new area developed recently by the cooperation between
economists, mathematicians and physicists. It’s not a tool to predict future prices
of stocks and exchange rates. It applies . . . . .
In these notes the main theoretical concepts and techniques in the field of mean-field spin-glasses are reviewed in a compact and pedagogical way, for the benefit of the graduate and undergraduate stu . . . . .
Chain-like macromolecules (polymers) show characteristic adsorption properties due to their flexibility and internal degrees of freedom, when attracted to surfaces and interfaces. In this review we di . . . . .
