On the giant magnon and spike solutions for strings on AdS3× S3
Abstract
We study solutions for the rotating strings on the sphere with a background NS-NS field and on the Anti-de-Sitter spacetime. We show the existence of magnon and single spike solutions on R×S2 in the presence of constant magnetic field as two limiting cases. We also study the solution for strings on AdS3× S3 with Melvin deformation. The dispersion relations among various conserved charges are shown to receive finite corrections due to the deformation parameter. We further study the rotating string on AdS3 × S3 geometry with two conserved angular momenta on S3 and one spin along the AdS3. We show that there exists two kinds of solutions: a circular string solution and a helical string. We find out the dispersion relation among various charges and give physical interpretation of these solutions.
