Spin Matrix theory string backgrounds and Penrose limits of AdS/CFT

A bstract Spin Matrix theory (SMT) limits provide a way to capture the dynamics of AdS/CFT correspondence near BPS bounds. On string side, these result in non-relativistic sigma models that can be interpreted as novel strings. This SMT couples U(1)-Galilean background geometries. In this paper, we explore relation between pp-wave backgrounds obtained from Penrose AdS 5 × S , and new type call flat-fluxed (FF) backgrounds. These FF are simplest possible correspond free magnons spin chain perspective. We catalogue one obtains on subsequently study large charge geometries which emerge. show analogous demonstrate charge/Penrose commute with limits. Finally, point out prescribe symplectic manifold for transverse embedding fields. is illustrated Hamiltonian derivation limit particle.
