Sequential flows by irrelevant operators
We explore whether one can $T\overline{T}$ deform a collection of theories that are already $T\overline{T}$-deformed. This allows us to define classes of irrelevant deformations that know about subsystems. In some basic cases, we explore the spectrum that results from this procedure and we provide n...

| description | We explore whether one can $T\overline{T}$ deform a collection of theories that are already $T\overline{T}$-deformed. This allows us to define classes of irrelevant deformations that know about subsystems. In some basic cases, we explore the spectrum that results from this procedure and we provide numerical evidence in favor of modular invariance. We also study the flow of the classical Lagrangian for free bosons and free fermions under successive deformations. Some of the models found by sequentially flowing are likely to have interesting holographic interpretations. |
