DESCRIPTION:Speakers: Arpita Mitra (CTP NAS\, Mahidol University\, Nakhon 
 Sawan campus)\nDespite significant advances in post-Minkowskian gravity\, 
 scattering-amplitude methods\, and gravitational-wave modeling\, existing 
 frameworks largely assume vacuum binary dynamics and do not systematically
  incorporate coherent environmental effects. We develop a unified Hamilton
 ian framework for compact binaries embedded in coherent ultralight dark ma
 tter\, combining post-Minkowskian gravity with Hamiltonian deformation the
 ory\, the classical interaction picture\, and the Magnus expansion. The re
 sulting eikonal captures dark matter–induced corrections to gravitationa
 l-wave observables\, providing a systematic framework and potential avenue
  for probing ultralight dark matter with gravitational-wave observations.\
