Pseudo entropy of primary operators in T T ¯ / J T ¯ $$ T\overline{T}/J\overline{T} $$ -deformed CFTs

Abstract In this work, we investigate the time evolution of the pseudo-(Rényi) entropy after local primary operator quenches in 2D CFTs with T T ¯ / J T ¯ $$ T\overline{T}/J\overline{T} $$ -deformation. Using perturbation theory, we analyze the corrections to the second pseudo-Rényi entropy at the l...
