Determining system Hamiltonian from eigenstate measurements without correlation functions

Determining system Hamiltonian from eigenstate measurements without correlation functions

Local Hamiltonians arise naturally in physical systems. Despite their seemingly ‘simple’ local structures, exotic features such as non-local correlations and topological orders exhibit in eigenstates of these systems. Previous studies for recovering local Hamiltonians from measurements on an eigenst...
