Improved Thermal Area Law and Quasilinear Time Algorithm for Quantum Gibbs States
One of the most fundamental problems in quantum many-body physics is the characterization of correlations among thermal states. Of particular relevance is the thermal area law, which justifies the tensor network approximations to thermal states with a bond dimension growing polynomially with the sys...
