Abstract

We elaborate on the resurgence analysis on the TT¯-deformed 2D conformal field theory (CFT). Writing the deformed partition function as an infinite series in the deformation parameter λ, we develop efficient analytical methods to compute high-order terms of the λ-series. Based on the asymptotic behavior of the large-order perturbative series, we show that the λ-series is asymptotic and extract nonperturbative contributions by resurgence. This paper extends a previous Letter of the same authors to interacting rational CFTs, with Lee-Yang CFT as a concrete example. We also discuss possible implications of the resurgence results on holography.
