Lie Algebra Expansion and Integrability in Superstring Sigma-Models
Andrea Fontanella, Luca Romano
Lie algebra expansion is a technique to generate new Lie algebras from a given one. In this paper, we apply the method of Lie algebra expansion to superstring -models with a $\m…
The Effectiveness of Relativistic Invariance in AdS
Andrea Fontanella, Olof Ohlsson Sax, Bogdan Stefański +2
We use relativistic invariance to investigate two aspects of integrable AdS string theory. Firstly, we write down the all-loop TBA equations for the massless sector of the th…
Black Horizons and Integrability in String Theory
Andrea Fontanella
This thesis is devoted to the study of geometric aspects of black holes and integrable structures in string theory. In the first part, symmetries of the horizon and its bulk extens…
Massless scattering and Bethe ansatz
Andrea Fontanella, Alessandro Torrielli
We first analyse the integrable scattering theory describing the massless excitations of superstrings in the relativistic limit. The matrix part of th…
