Recent experimental and theoretical progress has elucidated the tunable crossover, in ultracold Fermi gases, from BCS-type superconductors to BEC-type superfluids. The BCS-BEC Crossover and the Unitary Fermi Gas is a collaborative effort by leading international experts to provide an up-to-date introduction and a comprehensive overview of current research in this fast-moving field. It is now understood that the unitary regime that lies right in the middle of the crossover has remarkable universal properties, arising from scale invariance, and has connections with fields as diverse as nuclear physics and string theory. This volume will serve as a first point of reference for active researchersin the field, and will benefit the many non-specialists and graduate studentswho require a self-contained, approachable exposition of the subject matter.. Edited and authored by leading researchers in the field. Comprehensive andstate-of-the-art coverage of this emerging topic. Pedagogically written chapters make this volume suitable for courses and self-study INDICE: BEC-BCS Crossover and the Unitary Fermi Gas. BEC-BCS Crossover: Some History and General Considerations. Crossovers in Unitary Fermi Systems. Symmetry Properties of the Unitary Gas. Universal Relations for Fermions With Large Scattering Lenth. The Unitary Fermi Gas: Epsilon-Expansion, Nonrelativistic CFT. Dilute Fermi and Bose Gases. The Unitary Fermi Gas: From Quantum Monte Carlo to Density Functionals. Diagrammatic Pairing Fluctuation approach to theBCS-BEC Crossover. Normal Phase of Polarised Strongly Interacting Fermi Gases. BCS-BEC Crossover and Unconventional Superfluid Order in One Dimension. Scaling Flows and Dissipation in the Dilute Fermi Gas at Unitarity.
