Revisiting the O(3) Non-linear Sigma Model and Its Pohlmeyer Reduction
Georgios Pastras
It is well known that sigma models in symmetric spaces accept equivalent descriptions in terms of integrable systems such as the sine-Gordon equation through Pohlmeyer reduction. I…

Static Elliptic Minimal Surfaces in AdS(4)
Georgios Pastras
The Ryu-Takayanagi conjecture connects the entanglement entropy in the boundary CFT to the area of open co-dimension two minimal surfaces in the bulk. Especially in AdS(4), the lat…

On Elliptic String Solutions in AdS(3) and dS(3)
Ioannis Bakas, Georgios Pastras
Classical string actions in AdS(3) and dS(3) can be connected to the sinh-Gordon and cosh-Gordon equations through Pohlmeyer reduction. We show that the problem of constructing a c…
