Title:
A holistic approach to instantons on R^3 x S^1

Speaker:
Michael Ogilvie

Abstract:
Abelianizing deformations provide important tools for understanding the phase structure and topological excitations in both continuum and lattice field theories. Such deformations typically produce a rich phase structure, and allow additional analytic control over nonperturbative effects. In lattice models, Abelianizing deformations typically lead to the emergence of the constituents of instantons as primary objects. They can also provide a stabilizing mechanism for classically conformal theories, removing problems in the naive instanton expansion. Finally, Abelianizing deformations play a crucial role in phenomenological models of QCD at nonzero temperature and density, thus providing a bridge between theory and phenomenology.
