Quantum simulation for thermodynamics of infinite-size many-body systems by O(10) sites

3 Oct 2018 Shi-Ju Ran Bin Xi Cheng Peng Gang Su Maciej Lewenstein

In this work we propose to simulate many-body thermodynamics of infinite-size quantum lattice models in one, two, and three dimensions, in terms of few-body models of only O(10) sites, which we coin as quantum entanglement simulators (QES's). The QES is described by a temperature-independent Hamiltonian, with the boundary interactions optimized by the tensor network methods to mimic the entanglement between the bulk and environment in a finite-size canonical ensemble...
