6. 14. Lateral Superlattices in Commensurate Magnetic Fields: Electronic Structure, Transport and Optical Properties

   Author : Egidijus Anisimovas; Matematisk fysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; tunneling; Physics; collective excitations; optical absorption; quantum Hall effect; electronic structure; two-dimensional electron systems; lateral superlattices; Electromagnetism; Fysik; optics; acoustics; Elektromagnetism; optik; akustik; Fysicumarkivet A:2001:Anisimovas;

   Abstract : The present thesis is devoted to the theoretical study of two-dimensional electron systems moving in a modulated lateral periodic potential and a competing perpendicular magnetic field. The three introductory chapters offer a brief exposition of the basic issues in this area -- the description of the electron motion in a prependicular magnetic field, the group of magnetic translations and the commensurability phenomena -- at an elementary level.

7. 15. Electronic transitions and correlation effects : From pure elements to complex materials

   Author : Johan Jönsson; Igor A. Abrikosov; Marcus Ekholm; Sergei Dudarev; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electronic transition; solid state physics; condensed matter physics; correlation effects;

   Abstract : Macroscopic properties of real materials, such as conductivity, magneticproperties, crystal structure parameters, etc. are closely related or evendetermined by the configuration of their electrons, characterized by electronicstructure. By changing the conditions, e.g, pressure, temperature, magnetic/electric field, chemical doping, etc. READ MORE
