Journal Article
Cavaglià, A., Negro, S., Szécsényi, I. M., & Tateo, R. (2016). TT-deformed 2D quantum field theories. Journal of High Energy Physics, 2016(10), Article 112. https://doi.org/10.1007/jhep10%282016%29112

It was noticed many years ago, in the framework of massless RG flows, that the irrelevant composite operator T¯T, built with the components of the energy-momentum tensor, enjoys very special properties in 2D quantum field theories, and can be regarded...

Q-operators for the open Heisenberg spin chain (2015)
Journal Article
Frassek, R., & Szécsényi, I. M. (2015). Q-operators for the open Heisenberg spin chain. Nuclear Physics B, 901, 229-248. https://doi.org/10.1016/j.nuclphysb.2015.10.010

We construct Q-operators for the open spin-View the MathML source XXX Heisenberg spin chain with diagonal boundary matrices. The Q-operators are defined as traces over an infinite-dimensional auxiliary space involving novel types of reflection operat... Read More about Q-operators for the open Heisenberg spin chain.

Exact finite volume expectation values of local operators in excited states (2015)
Journal Article
Pozsgay, B., Szécsényi, I., & Takács, G. (2015). Exact finite volume expectation values of local operators in excited states. Journal of High Energy Physics, 2015(4), Article 23. https://doi.org/10.1007/jhep04%282015%29023

We present a conjecture for the exact expression of finite volume expectation values in excited states in integrable quantum field theories, which is an extension of an earlier conjecture to the case of general diagonal factorized scattering with bou...
