# SU(2) lattice gauge theory at nonzero chemical potential and temperature.

@article{Kogut2002SU2LG, title={SU(2) lattice gauge theory at nonzero chemical potential and temperature.}, author={J. B. Kogut}, journal={arXiv: High Energy Physics - Lattice}, year={2002}, volume={119}, pages={559-561} }

SU(2) lattice gauge theory with four flavors of quarks is simulated at nonzero chemical potential {mu} and temperature T and the results are compared to the predictions of Effective Lagrangians. Simulations on 16{sup 4} lattices indicate that at zero T the theory experiences a second order phase transition to a diquark condensate state which is well described by mean field theory. Nonzero T and {mu} are studied on 12{sup 3} x 6 lattices. For low T, increasing {mu} takes the system through a…
