Relating auxiliary field formulations of duality-invariant and integrable field theories
Nicola Baglioni, Daniele Bielli, Michele Galli +1
Auxiliary field techniques have recently gained interest in four-dimensional non-linear electrodynamics and two-dimensional integrable sigma models. In these settings, coupling a s…

Soliton Surfaces and the Geometry of Integrable Deformations of the Model
Christian Ferko, Michele Galli, Zejun Huang +1
The model is an analytically tractable quantum field theory which shares several properties with Yang-Mills theory. By virtue of its classical integra…

Higher-Spin Currents and Flows in Auxiliary Field Sigma Models
Daniele Bielli, Christian Ferko, Michele Galli +1
We study local, higher-spin conserved currents in integrable sigma models that have been deformed via coupling to auxiliary fields. These currents generate integrability-prese…
