One-loop quantization of rigid spinning strings in AdS3 × S3 × T 4 with mixed flux

Abstract We compute the one-loop correction to the classical dispersion relation of rigid closed spinning strings with two equal angular momenta in the AdS3 × S3 × T 4 background supported with a mixture of R-R and NS-NS three-form fluxes. This analysis is extended to the case of two arbitrary angular momenta in the pure NS-NS limit. We perform this computation by means of two...

Pulsating strings with mixed three-form flux

Abstract Circular strings pulsating in AdS3 × S3 × T 4 with mixed R-R and NS-NS three-form fluxes can be described by an integrable deformation of the one-dimensional Neumann-Rosochatius mechanical model. In this article we find a general class of pulsating solutions to this integrable system that can be expressed in terms of elliptic functions. In the limit of strings moving in...
