The Halon: A Quasiparticle Featuring Critical Charge Fractionalization

Boris Svistunov (University of Massachussetts Amherst)

I will present two quite different examples of a new impurity driven quantum criticality associated with a sharply defined integer charge of a quasiparticle (polaron). On the approach to the critical point, the charge distribution splits into a fractionally charged core and a critically large halo carrying the complementary charge.
