Contribution
It provides a detailed characterization of string chaos in Reissner-Nordstrom black hole backgrounds, highlighting the complex dynamical features in these settings.
Findings
String motion exhibits strong chaos in charged black hole backgrounds.
Lyapunov exponents quantify the sensitivity to initial conditions.
Chaotic behavior is consistent across AdS and flat spacetime geometries.
Abstract
We study the motion of a string in the background of Reissner-Nordstrom black hole, in both AdS as well as asymptotically flat spacetimes. We describe the phase space of this dynamical system through largest Lyapunov exponent, Poincare sections and basins of attractions. We observe that string motion in these settings is particularly chaotic and comment on its characteristics.
