A Non-Relativistic Limit of NS-NS Gravity
Eric Bergshoeff, Johannes Lahnsteiner, Luca Romano +2
We discuss a particular non-relativistic limit of NS-NS gravity that can be taken at the level of the action and equations of motion, without imposing any geometric constraints by…

String Theory and String Newton-Cartan Geometry
Eric Bergshoeff, Jaume Gomis, Jan Rosseel +2
Nonrelativistic string theory is described by a sigma model with a relativistic worldsheet and a nonrelativistic target spacetime geometry, that is called string Newton-Cartan geom…

An Action for Extended String Newton-Cartan Gravity
Eric Bergshoeff, Kevin Grosvenor, Ceyda Simsek +1
We construct an action for four-dimensional extended string Newton-Cartan gravity which is an extension of the string Newton-Cartan gravity that underlies nonrelativistic string th…
