“…For this purpose, it is essential to include Ramond-Ramond charges in the framework of NR string theory and to further explore the different pbrane limits generalizing the NR string limit that were discussed in Section 4.3. It would also be interesting to understand the relation to the recent construction of NR theories from null reduction of M5branes [114][115][116].…”

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 symmetries acting on the worldsheet fields. This theory arises as a self-contained corner of relativistic string theory. It has a string spectrum with a Galilean dispersion relation, and a spacetime S-matrix with nonrelativistic symmetry. This string theory also gives a unitary and ultraviolet complete framework that connects different corners of string theory, including matrix string theory and noncommutative open strings. In recent years, there has been a resurgence of interest in the non-Lorentzian geometries and quantum field theories that arise from nonrelativistic string theory in background fields. In this review, we start with an introduction to the foundations of nonrelativistic string theory in flat spacetime. We then give an overview of recent progress, including the appropriate target-space geometry that nonrelativistic strings couple to. This is known as (torsional) string Newton–Cartan geometry, which is neither Lorentzian nor Riemannian. We also give a review of nonrelativistic open strings and effective field theories living on D-branes. Finally, we discuss applications of nonrelativistic strings to decoupling limits in the context of the AdS/CFT correspondence.

“…This proposal was subsequently studied in many papers, see for example [32,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20]. Another, seemeangly different approach for definition of non-relativistic string theory, was presented in remarkable paper [4] where non-relativistic string in torsional Newton-Cartan background was defined by null dimensional reduction from higher dimensional space-time with light-like isometry, for further works see for example [21,22,23,24,25,26,27,28,29,30,31]. Finally the relation between these two seamingly different non-relativistic string theories was found in [13].…”
