Anomalous decay rate of quasinormal modes

Abstract:

The decay timescales of the quasinormal modes of a massive scalar field have an intriguing behavior: they either grow or decay with increasing angular harmonic numbers ℓ, depending on whether the mass of the scalar field is small or large. We identify the properties of the effective potential of the scalar field that leads to this behavior and characterize it in detail. If the scalar field is nonminimally coupled, considered here, the scalar quasinormal modes will leak into the gravitational ...
