Abstract:Chaos is ubiquitous to a wide range of physical systems with large number of degree of freedom and is crucial to thermalization and relaxation of the system. The exponential growth of out-of-time-order correlators and pole-skipping in the retarded two-point correlation functions of energy density are two different signatures for quantum chaos. We study quantum chaos of rotating BTZ black holes in topologically massive gravity. We discuss the relationship between chaos parameters including Lyapunov exponents and butterfly velocities from OTOC and from pole-skipping analysis. We find a partial match between pole-skipping and the OTOC results in the high temperature regime. We also find that the velocity bound puts a chaos constraint on the gravitational Chern-Simons coupling.
