Classical chaotic scattering is a topic of fundamental interest in nonlinear physics due to the
numerous existing applications in fields such as celestial mechanics, atomic and nuclear …

In a recent paper [PVP Cunha, CAR Herdeiro, E. Radu, and HF Runarsson, Phys. Rev. Lett.
115, 211102 (2015).], it was shown that the lensing of light around rotating boson stars and …

We investigate the qualitative features of binary black hole shadows using the model of two
extremally charged black holes in static equilibrium (a Majumdar–Papapetrou solution). Our …

For the past decade there has been a considerable debate about the existence of chaos in
the mixmaster cosmological model. The debate has been hampered by the coordinate, or …

When gravitational fields are at their strongest, the evolution of spacetime is thought to be
highly erratic. Over the past decade debate has raged over whether this evolution can be …

We explore the chaotic behavior of particle motion in a black hole with quasitopological
electromagnetism. The chaos bound is found to be violated in the higher order expansion of …

Nowadays the Lyapunov exponents and Lyapunov dimension have become so widespread
and common that they are often used without references to the rigorous definitions or …

Spinning compact binaries are shown to be chaotic in the post-Newtonian expansion of the
two-body system. Chaos by definition is the extreme sensitivity to initial conditions and a …

By detecting gravitational wave signals from extreme mass ratio inspiraling sources (EMRIs)
we will be given the opportunity to check our theoretical expectations regarding the nature of …

We present a proof that a system consisting of any finite number of particles that move under
the action of a scalar potential at constant kinetic energy exhibits conjugate pairing of …
