Description
This talk explores the fate of the "confining" N=4 flux tube in the presence of a large R-charge.
Using the AdS/CFT correspondence, we examine how inserting this charge induces a non-analytic transition.
The flux tube loses its standard configuration, evolving into a highly excited, "deconfined" state.
We map this regime to the BMN limit and integrable open spin chains with reflecting boundaries.
Finally, we compute the generalized cusp anomalous dimension across all coupling regimes.
