CP_N Solitons in Quantum Hall Systems
Abstract
We will present here an elementary pedagogical introduction to solitons in quantum Hall systems. We begin with a brief introduction to both models and to quantum Hall (QH) physics. Then we focus on spin and layer-spin degrees of freedom in QH systems and point out that these are in fact fields for N=1 and N=3. Excitations in these degrees of freedom will be shown to be topologically non-trivial soliton solutions of the corresponding field equations. This is followed by a brief summary of our own recent work in this area, done with Sankalpa Ghosh.
