Conservative Tidal Effects in Compact Binary Systems to Next-to-Leading Post-Minkowskian Order

Gregor Kälin, Zhengwen Liu, Rafael A. Porto

Using the Effective Field Theory approach together with the Boundary-to-Bound map, we compute the next-to-leading order (NLO) Post-Minkowskian (PM) tidal effects in the conservativ…

Conservative Dynamics of Binary Systems to Third Post-Minkowskian Order from the Effective Field Theory Approach

Gregor Kälin, Zhengwen Liu, Rafael A. Porto

We derive the conservative dynamics of non-spinning binaries to third Post-Minkowskian order, using the Effective Field Theory (EFT) approach introduced in [2006.01184] together wi…

Post-Minkowskian Effective Field Theory for Conservative Binary Dynamics

Gregor Kälin, Rafael A. Porto

We develop an Effective Field Theory (EFT) formalism to solve for the conservative dynamics of binary systems in gravity via Post-Minkowskian (PM) scattering data. Our framework co…

From Boundary Data to Bound States II: Scattering Angle to Dynamical Invariants (with Twist)

Gregor Kälin, Rafael A. Porto

We recently introduced in [1910.03008] a "boundary-to-bound" dictionary between gravitational scattering data and observables for bound states of non-spinning bodies. In this paper…

From Boundary Data to Bound States

Gregor Kälin, Rafael A. Porto

We introduce a -- somewhat holographic -- dictionary between gravitational observables for scattering processes (measured at the "boundary") and adiabatic invariants for bound orbi…
