Two-parameter integrable deformations of the AdS3 × S3 × T4 superstring
Abstract For supercosets with isometry group of the form G ̂ $$ \hat{\mathrm{G}} $$ × G ̂ $$ \hat{\mathrm{G}} $$ , the η-deformation can be generalised to a two-parameter integrable deformation with independent q-deformations of the two copies. We study its kappa-symmetry and write down a formula fo...

| description | Abstract For supercosets with isometry group of the form G ̂ $$ \hat{\mathrm{G}} $$ × G ̂ $$ \hat{\mathrm{G}} $$ , the η-deformation can be generalised to a two-parameter integrable deformation with independent q-deformations of the two copies. We study its kappa-symmetry and write down a formula for the Ramond- Ramond fluxes. We then focus on G ̂ $$ \hat{\mathrm{G}} $$ = PSU(1, 1|2) and construct two supergravity back- grounds for the two-parameter integrable deformation of the AdS3 × S3 × T4 superstring, as well as explore their limits. We also construct backgrounds that are solutions of the weaker generalised supergravity equations of motion and compare them to the literature. |
