Exponential Thermal Tensor Network Approach for Quantum Lattice Models
We speed up thermal simulations of quantum many-body systems in both one- (1D) and two-dimensional (2D) models in an exponential way by iteratively projecting the thermal density matrix ρ[over ^]=e^{-βH[over ^]} onto itself. We refer to this scheme of doubling β in each step of the imaginary time ev...
