Exact approaches on the string worldsheet
Saskia Demulder, Sibylle Driezen, Bob Knighton +5
We review different exact approaches to string theory. In the context of the Green-Schwarz superstring, we discuss the action in curved backgrounds and its supercoset formulation,…
More on the tensionless limit of pure-Ramond-Ramond AdS3/CFT2
Alberto Brollo, Dennis le Plat, Alessandro Sfondrini +1
In a recent letter we presented the equations which describe tensionless limit of the excited-state spectrum for strings on supported by Ramond-Ramond f…
On mixed-flux worldsheet scattering in AdS3/CFT2
Sergey Frolov, Davide Polvara, Alessandro Sfondrini
Strings on AdS3xS3xT4 with mixed Ramond-Ramond and Neveu-Schwarz-Neveu-Schwarz flux are known to be classically integrable. This is a crucial property of this model, which cannot b…
Ground state energy of twisted superstring and the TBA
Sergey Frolov, Anton Pribytok, Alessandro Sfondrini
We use the lightcone superstring sigma model with fermions and bosons subject to twisted boundary conditions to find the ground state energy in th…
New Dressing Factors for AdS3/CFT2
Sergey Frolov, Alessandro Sfondrini
The worldsheet S matrix of strings on the background is almost entirely fixed by symmetries, up to five functions -- the dressing factors. These must sa…
Mirror Thermodynamic Bethe Ansatz for AdS3/CFT2
Sergey Frolov, Alessandro Sfondrini
We consider superstrings on the pure-Ramond-Ramond background. Using the recently-proposed dressing factors for the worldsheet S matrix, we formulate th…
