Description
We explore $(1+1)$-dimensional cold and dense single-flavor $\mathrm{SU}(2)$ gauge theory using uniform matrix product states. Ground states are obtained by minimizing the Hamiltonian using variational uniform matrix product states, both with and without a baryon chemical potential. Several thermodynamic quantities, including the pressure and the expectation value of the baryon density, are computed with remarkable precision. We further compute the quark distribution function in momentum space. We find that the infrared behavior at finite baryon density is described by a Tomonaga--Luttinger liquid. The Luttinger parameter is determined under certain assumptions.
