Poisson-Lie duals of the η-deformed AdS2 x S2 x T6 superstring

We investigate Poisson-Lie duals of the eta-deformed AdS(2) x S-2 x T-6 superstring. The eta-deformed background satisfies a generalisation of the type II supergravity equations. We discuss three Poisson-Lie duals, with respect to (V the full pau(1, 1 vertical bar 2) superalgebra, (ii) the full bosonic subalgebra and (iii) the Cartan subalgebra, for which the corresponding backgrounds are expected to satisfy the standard type II supergravity equations. The metrics and B-fields for the first two cases are the same and given by an analytic continuation of the lambda-deformed model on AdS(2) x S-2 x T-6 with the torus undeformed. However, the RR fluxes and dilaton will differ. Focusing on the second case we explicitly derive the background and show agreement with an analytic continuation of a known embedding of the lambda-deformed model on AdS(2) x S-2 in type II supergravity.
