Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Yuya Kusuki, Hirosi Ooguri, Sridip Pal, , | Summary: We use the thermal effective theory to prove that, for the vacuum state in any conformal field theory in $d$ dimensions, the $n$-th R’enyi entropy $S_A^{(n)}$ behaves as $S_A^{(n)} = frac{f}{(2pi n)^{d-1}} frac{ {rm Area}(partial A)}{(d-2)epsilon^{d-2}}left(1+O(n)right)$ in the […]
