I 'm interested in Theoretical High Energy Physics, especially in
· Gauge - Gravity Duality
· Entanglement Entropy in QFT and in Holography
· Non – Linear Sigma Models & Integrable Systems
· Scattering Amplitudes and Fundamental Aspects of QFT.
I have worked on classical solutions of Non-Linear Sigma Models on Symmetric Spaces based on Pohlmeyer Reduction. In particular I contributed in developing techniques that enable the inversion of the Pohlmeyer Reduction, resulting in a systematic construction of all genus 1 classical string solutions in R x S2 (The method can be trivially generalized in higher dimensions). These results are relevant for many aspects of Ads – CFT Correspondence (Classical String Solutions, Ruy- Takayanagi conjecture in Ads4, Alday - Maldacena calculation of Scattering Amplitudes etc.). In addition the various classes of solutions can be treated in a universal way, which is a great advantage in comparison with the usual approaches.
I have contributed in the development of a perturbative approach, that supplements the method of Srednicki, for the calculation of Entanglement Entropy in QFT. In comparison with the usual replica trick treatment this method reconstructs the reduced density matrix of the theory, thus provides much more information.
