All-loop Bethe ansatz equations for AdS3/CFT2
Riccardo Borsato, Olof Ohlsson Sax, Alessandro Sfondrini
Using the S-matrix for the d(2,1;alpha)^2 symmetric spin-chain of AdS3/CFT2, we propose a new set of all-loop Bethe equations for the system. These equations differ from the ones p…
A dynamic su(1|1)^2 S-matrix for AdS3/CFT2
Riccardo Borsato, Olof Ohlsson Sax, Alessandro Sfondrini
We derive the S-matrix for the d(2,1;alpha)^2 symmetric spin-chain of AdS3/CFT2 by considering the centrally extended su(1|1)^2 algebra acting on the spin-chain excitations. The S-…
An introduction to universality and renormalization group techniques
Alessandro Sfondrini
These lecture notes have been written for a short introductory course on universality and renormalization group techniques given at the VIII Modave School in Mathematical Physics b…
Exceptional Operators in N=4 super Yang-Mills
Gleb Arutyunov, Sergey Frolov, Alessandro Sfondrini
We consider one particularly interesting class of composite gauge-invariant operators in N=4 super Yang-Mills theory. An exceptional feature of these operators is that in the Therm…
