Response Theory of the Electron-Phonon Coupling

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.

Various topics at the interface between condensed matter physics and the physics of ultra-cold fermionic atoms in optical lattices are discussed. Lectures given at the Enrico Fermi Summer School on 'Ultracold Fermi Gases' in 2006.

These notes cover the formalism of correlation functions and perturbation theory, adiabatic continuity and broken symmetry -- the most important basic principles of condensed matter physics, and modern problems and more recent calculational tools.

This paper reviews recent experimental and theoretical progress concerning many-body phenomena in dilute, ultracold gases. It focuses on effects beyond standard weak-coupling descriptions, such as the Mott-Hubbard transition in optical lattices, etc.

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.
