@article{Kusuki2018RenyiEF, title={Renyi entropy for local quenches in 2D CFT from numerical conformal blocks}, author={Yuya Kusuki and Tadashi Takayanagi}, journal={Journal of High Energy Physics}, year={2018}, volume={2018}, pages={1-22} }

A bstractWe study the time evolution of Renyi entanglement entropy for locally excited states in two dimensional large central charge CFTs. It generically shows a logarithmical growth and we compute the coefficient of log t term. Our analysis covers the entire parameter regions with respect to the replica number n and the conformal dimension hO of the primary operator which creates the excitation. We numerically analyse relevant vacuum conformal blocks by using Zamolodchikov’s recursion…
