The problem of the behavior of positrons and electrons in given external potentials, neglecting their mutual interaction, is analyzed by replacing the theory of holes by a reinterpretation of the solutions of the Dirac equation. It is possible to write down a complete solution of the problem in...
Related to Positrons:antimatter,Mesons,neutrinos pos·i·tron (pŏz′ĭ-trŏn′) n. An elementary particle having the same mass and magnitude of charge as an electron but exhibiting a positive charge; the antiparticle of the electron. Also calledantielectron. ...
Theory of Electrons and Positrons An electron, according to relativity quantum theory, has two different kinds of states of motion, those for which the kinetic energy is positive and those for which it is negative. Only the former, of course, can correspond to actual ele... PAM Dirac - 《...
Democritus' "atom" theory, after thousands of years of repeated times, finally found the material "atom" in the sense of scientific philosophy - "positrons, electrons" and their simplest combination photons, which is the basic unit of matter to build all things in ...

The behavior below Tc may be consistent with a Bardeen-Cooper-Schrieffer-like theory if an energy band with a small dispersion crosses the Fermi level. The discontinuity is not clearly understood, but may be due to a major change in the electronic structure taking place with the onset of ...
The spontaneous eye blink rate (EBR) has been linked to different cognitive processes and neurobiological factors. It has also been proposed as a putative index for striatal dopaminergic function. While estradiol is well-known to increase dopamine levels
