Abstract
The gravitational self-force theory, which takes a perturbative approach to the relativistic two-body problem with disparate masses, has emerged as the dominant method for modelling binary inspirals with asymmetric masses. This includes Extreme mass-ratio inspirals (a solar-mass neutron star or black hole orbiting a supermassive black hole) --- a key source for space-based gravitational-wave observatories (LISA, TianQin etc). This talk overviews how the self-force theory is used to model waveforms of extreme mass-ratio inspirals in practice. We will discuss the state of the art in this approach, with respect to its accuracy, efficiency, and coverage of the parameter space. These factors will be important for LISA scientific study.
