Non-relativistic string monodromies
Andrea Fontanella, Juan Miguel Nieto García, Olof Ohlsson Sax
Spectral curve methods proved to be powerful techniques in the context of relativistic integrable string theories, since they allow to derive the semiclassical spectrum from the mi…
On the singularities of the R-R AdS_3 x S^3 x T^4 S matrix
Olof Ohlsson Sax, Bogdan Stefanski
We investigate the analytic properties of the exact magnon S matrix of string theory on AdS_3 x S^3 x T^4 with R-R flux. We show that the previously proposed dressing factors have…
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…
Closed Strings and Moduli in
Olof Ohlsson Sax, Bogdan Stefanski
String theory on has 20 moduli. We investigate how the perturbative closed string spectrum changes as we move around this moduli space in both the RR…
Protected string spectrum in AdS3/CFT2 from worldsheet integrability
Marco Baggio, Olof Ohlsson Sax, Alessandro Sfondrini +2
We derive the protected closed-string spectra of AdS3/CFT2 dual pairs with 16 supercharges at arbitrary values of the string tension and of the three-form fluxes. These follow imme…
On the Dressing Factors, Bethe Equations and Yangian Symmetry of Strings on AdS3 x S3 x T4
Riccardo Borsato, Olof Ohlsson Sax, Alessandro Sfondrini +2
Integrability is believed to underlie the AdS3/CFT2 correspondence with sixteen supercharges. We elucidate the role of massless modes within this integrable framework. Firstly, we…
