Abstract We derive the thermal noise spectrum of longitudinal and transverse electric field operator a given wave vector starting from quantum-statistical definitions relate it to frequency dependent complex conductivity in homogeneous, isotropic system electromagnetic interacting charged particles frame non-relativistic QED. No additional assumptions except validity linear response are used pr...

The concepts of atoms and bonds in molecules which appeared in chemistry during the nineteenth century are unavoidable to explain the structure and the reactivity of the matter at a chemical level of understanding. Although they can be criticized from a strict reductionist point of view, because neither atoms nor bonds are observable in the sense of quantum mechanics, the topological and statis...

In this set of lectures, we give a pedagogical introduction to the subject of anyons. We discuss 1) basic concepts in anyon physics, 2) quantum mechanics of two anyon systems, 3) statistical mechanics of many anyon systems, 4) mean field approach to many anyon systems and anyon superconductivity , 5) anyons in field theory and 6) anyons in the Fractional Quantum Hall Effect (FQHE). ⋆ E-mail add...
