(m,n)-String and D1-Brane in Stringy Newton-Cartan Background

Understand

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.
