Title: Thermodynamic Bethe Ansatz for Konishi-like states in AdS_5 x S5
Date: Tue, Mar 09, 2010, 13:15 - 14:45
Place: Seminar Room A
Abstract: I review recent developments in the application of integrability methods to AdS/CFT correspondence between N=4 super Yang-Mills and superstring on AdS_5 x S5, with a focus on finite-size corrections to the asymptotic spectrum.
Recently, the exact spectrum of Konishi states in AdS_5 x S5 has been predicted based on Thermodynamic Bethe Ansatz (TBA),
which is a method to obtain the exact finite-volume spectrum in the integrable field theories in 1+1 dimensions. I discuss that
these TBA equations should take different forms depending on the 't Hooft coupling constant as well as the state under consideration. Existence of critical values of coupling constant may modify the exact
spectrum of Konishi and Konishi-like states.
