【Abstract】 Low dimensional and mesoscopic systems represent a major field of condensed matter physics. We first review some fundamental concepts and principles in mesoscopic physics, then describe recent progress in the study of quantum dots, two-dimensional gases, and electronic correlations in such systems. Some open questions are also pointed out.更多还原
