We review recent developments on nonrelativistic string theory. In flat spacetime, the theory
is defined by a two-dimensional relativistic quantum field theory with nonrelativistic global …

This study reviews the history of Newton–Cartan (NC) gravity with an emphasis on recent
developments, including the covariant, off-shell large speed of light expansion of general …

A bstract We study various aspects of the Carroll limit in which the speed of light is sent to
zero. A large part of this paper is devoted to the quantization of Carroll field theories. We …

Carroll symmetry arises from Poincaré symmetry upon taking the limit of vanishing speed of
light. We determine the constraints on the energy-momentum tensor implied by Carroll …

A bstract Non-relativistic string theories promise to provide simpler theories of quantum
gravity as well as tractable limits of the AdS/CFT correspondence. However, several …

A bstract We study the non-relativistic expansion of general relativity coupled to matter. This
is done by expanding the metric and matter fields analytically in powers of 1/c 2 where c is …

A bstract We find a Polyakov-type action for strings moving in a torsional Newton-Cartan
geometry. This is obtained by starting with the relativistic Polyakov action and fixing the …

A bstract 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 …

A bstract We construct various limits of JT gravity, including Newton-Cartan and Carrollian
versions of dilaton gravity in two dimensions as well as a theory on the three-dimensional …

A bstract 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 …
