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…
Bootstrapping the relativistic two-body problem
Christoph Dlapa, Gregor Kälin, Zhengwen Liu +1
We describe the formalism to compute gravitational-wave observables for compact binaries via the effective field theory framework in combination with modern tools from collider phy…
Symbol Alphabets from the Landau Singular Locus
Christoph Dlapa, Martin Helmer, Georgios Papathanasiou +1
We provide evidence through two loops, that rational letters of polylogarithmic Feynman integrals are captured by the Landau equations, when the latter are recast as a polynomial o…
Radiation Reaction and Gravitational Waves at Fourth Post-Minkowskian Order
Christoph Dlapa, Gregor Kälin, Zhengwen Liu +2
We obtain the total impulse in the scattering of non-spinning binaries in general relativity at fourth Post-Minkowskian order, i.e. , including linear, nonlinear, an…
Conservative Dynamics of Binary Systems at Fourth Post-Minkowskian Order in the Large-eccentricity Expansion
Christoph Dlapa, Gregor Kälin, Zhengwen Liu +1
We compute the conservative dynamics of non-spinning binaries at fourth Post-Minkowskian order in the large-eccentricity limit, including both potential and radiation-reaction tail…
Dynamics of Binary Systems to Fourth Post-Minkowskian Order from the Effective Field Theory Approach
Christoph Dlapa, Gregor Kälin, Zhengwen Liu +1
We present the contribution from potential interactions to the dynamics of non-spinning binaries to fourth Post-Minkowskian (4PM) order. This is achieved by computing the scatterin…
