Introduction to superfluidity : field-theoretic approach and applications / Andreas Schmitt.

By: Material type: TextTextSeries: Lecture notes in physics ; v 888.Publication details: Switzerland : Springer, 2015.Description: viii, 155 p. : illustrations (some color) ; 24 cmISBN:
  • 9783319079462 (hard cover : alk. paper)
Subject(s): DDC classification:
  • 530.42 23 Sch355
Contents:
1. Introduction -- 2. Superfluid Helium -- 3. Superfluidity in Quantum Field Theory -- 4. Relativistic Two-Fluid Formalism -- 5. Fermionic Superfluidity: Cooper Pairing -- 6. Meissner Effect in a Superconductor -- 7. BCS-BEC Crossover -- 8. Low-Energy Exitations in a Fermionic Superfluid -- 9. Cooper-Pairing with Mismatched Fermi Momenta -- References.
Summary: 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.
