Tensor network simulation of SU(2) lattice gauge theory in 2+1 dimensions

This paper demonstrates the feasibility of tensor network simulations for a 2+1 dimensional SU(2) lattice gauge theory including dynamical fermionic matter. The authors characterize the phase diagram at zero and finite baryon density. They find a baryon liquid phase with gapless excitations emerges at low quark mass. Traces of deconfinement and possible topological order are seen near maximal frustration of electric and magnetic terms.
