A subpolynomial-time algorithm for the free energy of one-dimensional quantum systems in the thermodynamic limit
We introduce a classical algorithm to approximate the free energy of local, translation-invariant, one-dimensional quantum systems in the thermodynamic limit of infinite chain size. While the ground state problem (i.e., the free energy at temperature $T = 0$) for these systems is expected to be comp...
