Quantum folded string and integrability: from finite size effects to Konishi dimension

Understand

Using the algebraic curve approach we one-loop quantize the folded string solution for the type IIB superstring in AdS(5)xS(5).

• We obtain an explicit result valid for arbitrary values of its Lorentz spin S and R-charge J in terms of integrals of elliptic functions.
• Then we consider the limit S ~ J ~ 1 and derive the leading three coefficients of strong coupling expansion of short operators.
• Notably, our result evaluated for the anomalous dimension of the Konishi state gives 2\lambda^{1/4}-4+2/\lambda^{1/4}.
