Path Integral Complexity in presence of Interaction.

14.06.2018 15:00 – 16:00

In this talk I will formulate a path-integral optimization for two-dimensional conformal field theories perturbed by relevant operators motivated by tensor network approach. I will present several evidences how this optimization mechanism works, based on calculations in free field theories as well as general arguments of RG flows in field theories. Our optimization is performed by minimizing the path-integral complexity functional that depends on the metric and also on the relevant couplings. Then, we compute the optimal metric perturbatively and find that it agrees with the time slice of the hyperbolic metric perturbed by a scalar field in the AdS/CFT correspondence. Last but not the least, we estimate contributions to complexity from relevant perturbations
