Description

I will discuss a generic, intrinsically topological phenomenon that arises in systems supporting transitions between distinct topological states, together with the corresponding fermionic zero modes. In particular, I will argue for the formation of a condensate of composite fermion operators that spontaneously breaks an anomalous symmetry. The phase of the condensate gives rise to a collective, propagating particle state, which is predicted to exist in the electroweak sector of the Standard Model, in the simplest supersymmetric extensions of General Relativity, and in condensed matter systems such as Weyl semimetals.
