This article presents a systematic theoretical enquiry concerning the conceptual foundations and the nature of phonon-mediated electron-electron interactions. Starting from the fundamental many-body Hamiltonian, we propose a simple scheme to decouple the electrons and nuclei of a crystalline solid via effective interactions.

Important progress in understanding the behavior of hadronic matter at high density has been achieved recently. We discuss the phase diagram of QCD as a function of temperature and density, and close with a look at possible astrophysical signatures.

These lecture notes give a pedagogical introduction to phase transitions in disordered quantum systems and to the exotic Griffiths phases induced in their vicinity. The author also presents a number of experimental examples.

This book introduces the theoretical description of quantum fluids. The focus is on gaseous atomic Bose-Einstein condensates and, to a minor extent, superfluid helium, but the underlying concepts are relevant to other forms of quantum fluids.
