Concentration bounds for quantum states with finite correlation length on quantum spin lattice systems
We consider the problem of determining the energy distribution of quantum states that satisfy exponential decay of correlation and product states, with respect to a quantum local Hamiltonian on a spin lattice. For a quantum state on a D -dimensional lattice that has correlation length σ and has aver...
