Quantum dots, sometimes called artificial atoms, are exquisite tools by which quantum behavior can be probed on a larger scale than the atomic, namely on the nanometer scale. While the physics exhibited by these devices is closer to classical than atomic physics, quantum dots are still sufficiently small to clearly exhibit quantum phenomena. This volume, intended for graduate students and young researchers, offers an introduction to many of these fascinating aspects. In the first lecture, R. Shankar treats the general theoretical aspects of Fermi liquids, in particular the renormalization...
