Title: T Tbar-deformed classical and quantum  field theories in two dimensions

Roberto Tateo (Dipartimento di Fisica , Università di Torino, Italie)

 

Abstract:   Surprising links between the deformation of 2D quantum field theories
induced by the composite $T \bar{T}$ operator, effective string models and
the AdS/CFT correspondence, have recently emerged.
I will discuss various classical and quantum aspects of this special
irrelevant perturbation, including  its  geometrical interpretation  at
classical level.  The deformed  sine-Gordon model is used as explanatory  
example.
