Expectation value of $\mathrm{T}\overline{\mathrm{T}}$ operator in curved spacetimes
We study the expectation value of the $ \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 $ \mathrm{T}\overline{\mathrm{T}} $ operator. We show that this biscalar is a...
