Correlation function of modular Hamiltonians
arXiv:1907.00646 · doi:10.1007/JHEP11(2019)163
Abstract
We investigate varies correlation functions of modular Hamiltonians defined with respect to spatial regions in quantum field theories. These correlation functions are divergent in general. We extract finite correlators by removing divergent terms for two dimensional massless free scalar theory. We reproduce the same correlators in general two dimensional conformal field theories.
