We analyze non-relativistic string in Newton-Cartan background that was found recently in
arXiv:1705.03535
. We find its Hamiltonian formulation and study structure of constraints. We also ...discuss a relation between string in Newton-Cartan Background and T-duality along null reduction.
We study string theory with momentum living on de Sitter space. We argue that consistency of the theory implies that the global momentum can be defined on de Sitter space. Then we perform careful ...canonical analysis and we we also show that this presumption leads to the string with deformed dispersion relation.

This paper is devoted to the analysis of (
m, n
)-string in stringy Newton-Cartan background. We start with the Hamiltonian constraint for (
m, n
)-string in general background and perform ...limiting procedure on metric and NSNS and Ramond-Ramond two form background that leads to stringy Newton-Cartan gravity. We also analyze conditions that these background fields have to obey in order to define consistent world-sheet (
m, n
)−theory. We also discuss D1-brane with dynamical electric field in stringy Newton-Cartan gravity.

In this note we perform canonical analysis of T-duality for non-relativistic string in stringy Newton-Cartan background. We confirm recent result that T-duality along longitudinal spatial ...direction of stringy Newton-Cartan geometry maps non-relativistic string to the relativistic string that propagates on the background with light-like isometry.
In this short note we analyze canonical description of T-duality along light-like isometry. We show that T-duality of relativistic string theory on this background leads to non-relativistic string ...theory action on T-dual background.

This paper is devoted to the construction of unstable D-brane action in torsional Newton-Cartan background through T-duality along null direction. We determine corresponding equations of ...motion and analyze their solution that corresponds to lower dimensional non-relativistic D(p-1)-brane. We also find Hamiltonian for unstable Dp-brane and study tachyon vacuum solutions that can be interpreted as gas of non-relativistic strings.
