Skyrmions and Hall Transport [Hardcover]

1. Symmetries of Magnetic Skyrmions 2. Background Materials: Hydrodynamics 3. Hall Viscosity 4. Spin Dynamics 5. First Principal Method: Ward Identity 6. Skyrmion Dynamics and Transport 7. Modeling Hall Viscosity for Skyrmions

This book provides an extensive account of skyrmion dynamics, using various analytical tools, especially the field theory Ward identity that is a first principle method using symmetries and the associated conservation equations. The identity revealed that Hall viscosity is a universal part of skyrmion motion.

Bom Soo Kim is an assistant professor at the University of WisconsinParkside, USA. He received his PhD in physics from the University of California at Berkeley, USA, and his BS in astronomy from Yonsei University, South Korea. He was trained as a postdoctoral researcher in a joint appointment with IESL-FORTH and the University of Crete, Greece, and then at the Tel Aviv University, Israel. He has been a teaching postdoc at the University of Kentucky and a full-time lecturer at Loyola University Maryland, USA. Although he is formally trained in theoretical high-energy physics utilizing quantum field theory and string theory, his research interests extend to condensed matter physics, materials science, and quantum information science. Dr Kim currently works on quantum entanglement, holographic renormalization, and in particular, physical systems without parity symmetry that include magnetic skyrmions.

In the past decade, the field of physics has witnessed renewed advances in physical systems without mirror (parity) symmetry. Firstly, the experimental discovery of chiral magnetic skyrmions has stirred a great deal of anticipation because their nanoscale size, topological protection, and energy efficiency make them an attractive candidate for cutting-edge spintronic applications. Secondly, the discovery of Hall viscosity, a new universal transport coefl£h
