Quasinormal modes and complexity in saddle-dominated SU(N) spin systems

Sergio E. Aguilar-Gutierrez, Yichao Fu, Kuntal Pal +1

We study SU($N$) spin systems that mimic the behavior of particles in $N$-dimensional de Sitter space for $N=2,3$. Their Hamiltonians describe a dynamical system with hyperbolic fi…
