High-precision theoretical predictions for the dynamics of compact binary systems are crucial for maximizing the scientific potential of current and future gravitational-wave observatories, including LIGO-Virgo-KAGRA, Taiji, TianQin, and the Einstein Telescope. Modern Quantum Field Theory (QFT) methods—particularly Effective Field Theory and multi-loop techniques—have emerged as powerful tools for addressing the classical two-body problem analytically. This talk will review recent developments in these methods and discuss their applications to classical gravity, from relativistic two-body scattering to the static potential.
