Quantum point particle approximation of spinning black holes and compact stars

Understand

Gravitational wave observatories targeted for compact binary coalescence, such as LIGO and VIRGO, require various theoretical inputs for their efficient detection.

• One of such inputs are analytical description of binary dynamics at sufficiently separated orbital scales, commonly known as post-Newtonian dynamics.
• One approach for determining such two-body effective Hamiltonians is to use quantum scattering amplitudes.
• This dissertation aims at an improved understanding of classical physics of spinning bodies in quantum scattering amplitudes, for application to the problem of effective two-body Hamiltonians.
