Title: Anyonic particle-vortex statistics and the nature of dense quark matter

Abstract

We show that Z3-valued particle-vortex braiding phases are present in high density quark matter. Certain mesonic and baryonic excitations, in the presence of a superfluid vortex, have orbital angular momentum quantized in units of ℏ/3. Such nonlocal topological features can distinguish phases whose realizations of global symmetries, as probed by local order parameters, are identical. If Z3 braiding phases and angular momentum fractionalization are absent in lower density hadronic matter, as is widely expected, then the quark matter and hadronic matter regimes of dense QCD must be separated by at least one phase transition.
