On $\sqrt{T\overline{T}}$ deformed pathways: CFT to CCFT

Aritra Banerjee, Pulastya Parekh, Robin Raj

A marginal √(TTbar) deformation of 2D massless scalar theories preserves relativistic conformal symmetries until special moduli points where the algebra transitions smoothly to Carrollian conformal symmetry.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The marginal deformation does not change the conformal symmetries of the theory, until some special points in the moduli space are reached, and the relativistic conformal algebra smoothly changes to the Carrollian conformal (equivalently BMS) one.

C2weakest assumption

That the operator flow equations induce a Legendre transformation between flowed Lagrangians and Hamiltonians that remains unchanged during the entire flow, allowing the symmetry transition to be tracked consistently from configuration and phase space.

C3one line summary

The marginal √(T T-bar) deformation of 2D massless scalars provides a dynamical map from relativistic CFT to Carrollian CCFT symmetries, recovering the electric Carroll theory and a novel magnetic counterpart in the extreme limits.
