Topology, chiral and screening transitions at finite density in two colour QCD
B. Alles, M. D'Elia, M. P. Lombardo
Abstract
The behaviour of the topological susceptibility in QCD with two colours and 8 flavours of quarks is studied at nonzero temperature on the lattice across the finite density transition. It is shown that its signal drops at a (pseudo-)critical chemical potential muc. The Polyakov loop and the chiral condensate undergo their transitions at the same value. Pauli blocking supervenes at a value of the chemical potential larger than muc.
