Two distinct phase transitions occur at different temperatures in QCD with adjoint fermions (aQCD): deconnement and chiral symmetry restoration. In this model, quarks do not explicitly break the center Z(3) symmetry and therefore the Polyakov loop is a good order parameter for the deconnement transition. We study monopole condensation by inspecting the expectation value of an operator which creates a monopole. Such a quantity is expected to be an order parameter for the deconnement transition as in the case of fundamental fermions.

Abstract
Two distinct phase transitions occur at different temperatures in QCD with adjoint fermions (aQCD): deconnement and chiral symmetry restoration. In this model, quarks do not explicitly break the center Z(3) symmetry and therefore the Polyakov loop is a good order parameter for the deconnement transition. We study monopole condensation by inspecting the expectation value of an operator which creates a monopole. Such a quantity is expected to be an order parameter for the deconnement transition as in the case of fundamental fermions.File in questo prodotto:
