Dressed D-strings with Instability and Transverse Rotation: The Open String Pair Production

Abstract

Motivated by the Schwinger effect in the QED, we investigate the open string pair creation for the dressed D1-branes, incorporating electric and tachyonic fields and also transverse rotation in the presence of the antisymmetric (Kalb-Ramond) background field. The background spacetime is partially compact on a torus. Our first observation is that the presence of the tachyonic field together with the transverse rotation prevents the open string production. Consequently, we shall quench the tachyonic field. Thus, we find that the pair creation arises only when the angular frequencies of the D-strings satisfy a rational relation. Besides, we observe that the compactification enhances the production rate of the open strings. Finally, we study various special cases of the system.
