From weak coupling to spinning strings

Understand

We identify the gauge theory dual of a spinning string of minimal energy with spins S_1, S_2 on AdS_5 and charge J on S^5.

• For this purpose we focus on a certain set of local operators with two different types of covariant derivatives acting on complex scalar fields.
• We analyse the corresponding nested Bethe equations for the ground states in the limit of large spins.
• The auxiliary Bethe roots form certain string configurations in the complex plane, which enable us to derive integral equations for the leading and sub-leading contribution to the anomalous dimension.
