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…
Non-extremal near-horizon geometries
Andrea Fontanella
When Gaussian null coordinates are adapted to a Killing horizon, the near-horizon limit is defined by a coordinate rescaling and then by taking the regulator parameter $\varepsilon…
Extending the non-relativistic string AdS coset
Andrea Fontanella, Juan Miguel Nieto García
Inspired by Lie algebra expansion, we consider an extension of the algebra introduced in arXiv:2203.07386 for the non-relativistic string coset action in AdSS. We sho…
Coset space actions for nonrelativistic strings
Andrea Fontanella, Stijn J. van Tongeren
We formulate the stringy nonrelativistic limits of the flat space and AdSS string as coset models, based on the string Bargmann and extended string Newton-Hooke algeb…
