On the non-BPS string solutions in Sasaki-Einstein gauge/gravity duality

Understand

We present an extensive analysis on several string solutions in AdS_5 x Ypq and find some interesting properties of their energy-spin relations.

• Their energy depends always on the parameter a(p,q) which characterizes these manifolds.
• The range of this parameter for the string solutions is constrained by the Sasaki-Einstein constraints that the solutions should satisfy.
• Hence some string solutions we find are not valid for the whole class of Ypq manifolds.
