Classical and quantum integrability in AdS(2)/CFT(1)

Understand

We investigate the type IIA string on AdS(2)xS(2)xT(6) supported by RR-flux which describes the gravitational side of the AdS(2)/CFT(1) correspondence.

• While the four-dimensional part AdS(2)xS(2) can be realized as a supercoset, the full superstring has both coset and non-coset excitations, the latter giving rise to massless worldsheet modes, a somewhat novel feature in AdS/CFT.
• The string is nevertheless known to be integrable at the classical level.
• In this paper we perform several computations checking aspects of both classical and quantum string integrability.
