Nonlocal-in-time tail effects in gravitational scattering to fifth Post-Minkowskian and tenth self-force orders
Christoph Dlapa, Gregor Kälin, Zhengwen Liu +1
Using the worldline effective field theory formalism, we derive the nonlocal-in-time conservative contributions arising from tail effects in gravitational scattering to fifth Post-…

Local-in-Time Conservative Binary Dynamics at Fifth Post-Minkowskian and First Self-Force Orders
Christoph Dlapa, Gregor Kälin, Zhengwen Liu +1
We report the local-in-time conservative dynamics of nonspinning binary systems at fifth Post-Minkowskian (5PM) and first self-force (1SF) orders. This follows from an explicit cal…

Local-in-time Conservative Binary Dynamics at Fourth Post-Minkowskian Order
Christoph Dlapa, Gregor Kälin, Zhengwen Liu +1
Leveraging scattering information to describe binary systems in generic orbits requires identifying local- and nonlocal-in-time tail effects. We report here the derivation of the u…
