Expectation value of T T ¯ $$ \mathrm{T}\overline{\mathrm{T}} $$ operator in curved spacetimes
Abstract We study the expectation value of the T T ¯ $$ \mathrm{T}\overline{\mathrm{T}} $$ operator in maximally symmetric spacetimes. We define an diffeomorphism invariant biscalar whose coinciding limit gives the expectation value of the T T ¯ $$ \mathrm{T}\overline{\mathrm{T}} $$ operator. We sho...
