Vortices in unconventional superconductors and superfluids

The physics of vortices in classical fluids has long been significant in both fundamental science and engineering. Approximately 50 years ago, vortices emerged as quantum mechanical entities derived from a macroscopic wavefunction, with key contributions from R. Feynman, L. Onsager, L. D. Landau, F. London, V. L. Ginzburg, and A. A. Abrikosov. Recently, the study of vortices has expanded into unconventional superconductors and superfluids, characterized by anisotropic and complex order parameters. This book addresses this latest evolution in vortex physics. It comprises 20 chapters, each authored by experts in their respective fields, focusing on the microscopic structure and dynamics of vortices across various systems, including superfluids, superconductors, and neutron stars. Each chapter offers an introduction and overview, highlighting both theoretical and experimental work, and includes references to recent and foundational studies. This approach ensures that non-expert readers can also gain insights from the material. Consequently, the book serves as a valuable resource for researchers and graduate students interested in vortex physics in unconventional superconductors and superfluids, and it may also be used as supplementary material for graduate courses in low-temperature solid-state physics.
