Soliton Surfaces and the Geometry of Integrable Deformations of the ${\mathbb{CP}}^{N-1}$ Model

Christian Ferko, Michele Galli, Zejun Huang +1

The ${\mathbb{CP}}^{N-1}$ model is an analytically tractable $2d$ quantum field theory which shares several properties with $4d$ Yang-Mills theory. By virtue of its classical integra…
