-deformed Nonlinear Schrödinger
Paolo Ceschin, Riccardo Conti, Roberto Tateo
The -deformed classical Lagrangian of a 2D Lorentz invariant theory can be derived from the original one, perturbed only at first order by the bare $\text{T…
Counting monster potentials
Riccardo Conti, Davide Masoero
We study the large momentum limit of the monster potentials of Bazhanov-Lukyanov-Zamolodchikov, which -- according to the ODE/IM correspondence -- should correspond to excited stat…
Geometry of random potentials: Induction of 2D gravity in Quantum Hall plateau transitions
Riccardo Conti, Hrant Topchyan, Roberto Tateo +1
In the context of the Integer Quantum Hall plateau transitions, we formulate a specific map from random landscape potentials onto 2D discrete random surfaces. Critical points of th…
Conserved currents and irrelevant deformations of 2D integrable field theories
Riccardo Conti, Stefano Negro, Roberto Tateo
It has been recently discovered that the deformation is closely-related to Jackiw-Teitelboim gravity. At classical level, the introduction of this perturba…
The perturbation and its geometric interpretation
Riccardo Conti, Stefano Negro, Roberto Tateo
Starting from the recently-discovered -perturbed Lagrangians, we prove that the deformed solutions to the classical EoMs for bosonic field theories are…
Generalised Born-Infeld models, Lax operators and the perturbation
Riccardo Conti, Leonardo Iannella, Stefano Negro +1
Surprising links between the deformation of 2D quantum field theories induced by the composite operator, effective string models and the CFT cor…
