Walls of massive K\"ahler sigma models on SO(2N)/U(N) and Sp(N)/U(N)
Abstract
We study the Bogomol'nyi-Prasad-Sommerfield wall solutions in massive K\"ahler nonlinear sigma models on SO(2N)/U(N) and Sp(N)/U(N) in three-dimensional spacetime. We show that SO(2N)/U(N) and Sp(N)/U(N) models have 2N-1 and 2N discrete vacua, respectively. We explicitly construct the exact BPS multiwall solutions for N 3.
