# The 2D Volkov-Akulov model as a $T \bar{T}$ deformation

## TL;DR

This paper demonstrates that the 2D $N=(2,2)$ Volkov-Akulov model, describing spontaneous supersymmetry breaking, can be viewed as a $Tar{T}$ deformation of a free fermionic theory, suggesting a link between nonlinear supersymmetry and $Tar{T}$ flows.

## Contribution

It establishes that the Volkov-Akulov model is a $Tar{T}$ deformation of a free fermionic theory, revealing a new connection between nonlinear supersymmetry and $Tar{T}$ deformations.

## Key findings

- The Volkov-Akulov action is a $Tar{T}$ deformation of a free fermionic theory.
- Indicates a potential relation between nonlinear supersymmetry and $Tar{T}$ flows.
- Provides a new perspective on supersymmetry breaking models.

## Abstract

We show that the two-dimensional $N=(2,2)$ Volkov-Akulov action that describes the spontaneous breaking of supersymmetry is a $T\bar{T}$ deformation of a free fermionic theory. Our findings point toward a possible relation between nonlinear supersymmetry and $T \bar T$ flows.
