Semiclassical rigid strings with two spins in AdS_5

Understand

Semiclassical spinning string states in AdS_5 are, in general, characterised by the three SO(2,4) conserved charges: the energy E and the two spins S_1 and S_2.

• We discuss several examples of explicit classical solutions for rigid closed strings of (bended) circular shape with two non-zero spins.
• In particular, we identify a solution that should represent a state that has minimal energy for large values of the two equal spins.
• Similarly to the spiky string in AdS_3, in the large spin limit this string develops long "arcs" that stretch towards the boundary of AdS_5.
