Numerical simulation of high quark densities in QCD with two colours
arXiv:hep-lat/0112046
Abstract
The DESY-Swansea Collaboration performed numerical simulations investigating SU(2) lattice gauge theory at non-zero chemical potential with one staggered quark flavour in the adjoint representation. This lattice model has similar features to QCD itself and its study gives interesting insights into some open problems of high density quark matter. In particular the role of the ``sign problem'' can be clarified in connection with diquark condensation and the phase diagram.
