trailIn a 2+1D lattice gauge theory with fundamental scalars, the phase of a vortex-line correlator linking a Wilson line changes non-analytically between Higgs and confining regimes
The physically meaningful Aharonov-Bohm phase of a test quark in a superfluid is that of the dressed charge
Nonanalytic behavior of gauge-invariant correlation functions marks a physical distinction between phases
Physical distinctions between phases must be detectable by measurements on finite-energy physical states
+1
Vortex Aharonov-Bohm phases can be measured as order parameters in lattice simulations of gauge-Higgs models
