Quantum string test of nonconformal holography

We compute Lüscher corrections to the effective string tension in the PilchWarner background, holographically dual to \( \mathcal{N} \) = 2∗ supersymmetric Yang-Mills theory. The same quantity can be calculated directly from field theory by solving the localization matrix model at large-N . We find complete agreement between the field-theory predictions and explicit string-theory ...

Deformed Neumann model from spinning strings on (AdS5 × S5) η

We show that bosonic spinning strings on the η-deformed AdS5 × S5 background are naturally described as periodic solutions of a novel finite-dimensional integrable system which can be viewed as a deformation of the celebrated Neumann model. For this deformed model we find the Lax representation and the analogue of the Uhlenbeck integrals.
