Manifestations of Berry`s phase in molecules and condensed matter
... The Berry’s phase is almost ubiquitous in present-day physics: because of this, unavoidably the Berry’s phase means somewhat different things to different people. Here we narrow the focus to the geometric quantum phases of many-electron systems and their observable effects. Even after thus narrowing ...

Landau`s Fermi Liquid Theory
... The concept of a Fermi Liquid describes (strongly) interacting fermions using concepts that naively would only be applicable to a very weakly interacting gas. That this is at all possible makes Fermi Liquid theory a very versatile, but at the same time its very success is puzzling. Fermi Liquid theo ...

Chapter 1. Some experimental facts
... If ν was to become much higher than UV it would become first X-rays and then gamma rays. The walls of the enclosure would be permeable to such radiation. Also the temperature of the wall would have to be much higher and the enclosure would melt and vaporize. From relativity we know that a particle o ...

Theoretical and experimental status of magnetic monopoles

Applying (1.4) to this operator, we have δψ a = ((â − aψ I)2 ψ, ψ) = ((â − aψ I)ψ, (â − aψ I)ψ) = âψ − aψ 2 . Now we have the following important Claim 1.5.
