Open AccessLongitudinal Galilean and Carrollian limits of non-relativistic strings
It is well known that one can take an infinite speed of light limit that gives rise to non-relativistic strings with a relativistic worldsheet sigma model but with a non-relativistic target space geometry. In ...

Open AccessTorsional string Newton-Cartan geometry for non-relativistic strings
We revisit the formulation of non-relativistic (NR) string theory and its target space geometry. We obtain a new formulation in which the geometry contains a two-form field that couples to the tension current ...

Open AccessNon-Riemannian isometries from double field theory
We explore the notion of isometries in non-Riemannian geometries. Such geometries include and generalise the backgrounds of non-relativistic string theory, and they can be naturally described using the formali...

Open AccessSpin Matrix theory string backgrounds and Penrose limits of AdS/CFT
Spin Matrix theory (SMT) limits provide a way to capture the dynamics of the AdS/CFT correspondence near BPS bounds. On the string theory side, these limits result in non-relativistic sigma models that can be ...

Open AccessRelating non-relativistic string theories
Non-relativistic string theories promise to provide simpler theories of quantum gravity as well as tractable limits of the AdS/CFT correspondence. However, several apparently distinct non-relativistic string t...

Open AccessZooming in on AdS3/CFT2 near a BPS bound
Any (d + 1)-dimensional CFT with a U(1) flavor symmetry, a BPS bound and an exactly marginal coupling admits a decoupling limit in which one zooms in on the spectrum close to the bound. This limit is an Inönü-Wig...

Open AccessGeneralized Toda theory from six dimensions and the conifold
Recently, a physical derivation of the Alday-Gaiotto-Tachikawa correspondence has been put forward. A crucial role is played by the complex Chern-Simons theory arising in the 3d-3d correspondence, whose bounda...
