Signature of nonuniform area quantization on gravitational waves

Abstract

Quantum aspects of black holes may have observational imprints on their absorption and emission spectrum. In this work, we consider the possibility of nonuniform area quantization and its effects on the phasing of a gravitational waveform from coalescing black hole inspirals. These observations may provide detectable effects distinct from that of a uniform area quantization and allow us to put bounds on various parameters of the underlying model. Our work can also be regarded as a novel test for the area-entropy proportionality of black hole solutions in general relativity.
