Introduction to Superfluidity

Introduction to Superfluidity Field-theoretical Approach and Applications / [electronic resource] : by Andreas Schmitt. - VIII, 155 p. 26 illus., 11 illus. in color. online resource. - Lecture Notes in Physics, 888 0075-8450 ; . - Lecture Notes in Physics, 888 .
Introduction -- Superfluid Helium -- Superfluidity in Quantum Field Theory -- Relativistic Two-Fluid Formalism -- Fermionic Superfluidity: Cooper Pairing -- Meissner Effect in a Superconductor -- BCS-BEC Crossover -- Low-Energy Exitations in a Fermionic Superfluid -- Cooper-Pairing with Mismatched Fermi Momenta -- References.
Superfluidity – and closely related to it, superconductivity – are very general phenomena that can occur on vastly different energy scales. Their underlying theoretical mechanism of spontaneous symmetry breaking is even more general and applies to a multitude of physical systems. In these lecture notes, a pedagogical introduction to the field-theory approach to superfluidity is presented. The connection to more traditional approaches, often formulated in a different language, is carefully explained in order to provide a consistent picture that is useful for students and researchers in all fields of physics. After introducing the basic concepts, such as the two-fluid model and the Goldstone mode, selected topics of current research are addressed, such as the BCS-BEC crossover and Cooper pairing with mismatched Fermi momenta.
