AlphaFold predicts the most complex protein knot and composite protein knots
Maarten A. Brems, Robert Runkel, Todd O. Yeates +1
The computer artificial intelligence system AlphaFold has recently predicted previously unknown three-dimensional structures of thousands of proteins. Focusing on the subset with h…
Feynman integrals for binary systems of black holes
Philipp Alexander Kreer, Robert Runkel, Stefan Weinzierl
The initial phase of the inspiral process of a binary black-hole system can be described by perturbation theory. At the third post-Minkowskian order a two-loop double box graph, kn…
A new formulation of the loop-tree duality at higher loops
Robert Runkel, Zoltán Szőr, Juan Pablo Vesga +1
We present a new formulation of the loop-tree duality theorem for higher loop diagrams valid both for massless and massive cases. -loop integrals are expressed as weighted sum o…
Integrands of loop amplitudes within loop-tree duality
Robert Runkel, Zoltán Szőr, Juan Pablo Vesga +1
Using loop-tree duality, we relate a renormalised -point -loop amplitude in a quantum field theory to a phase-space integral of a regularised -fold forward limit of a UV-s…
Causality and loop-tree duality at higher loops
Robert Runkel, Zoltán Szőr, Juan Pablo Vesga +1
We relate a -loop Feynman integral to a sum of phase space integrals, where the integrands are determined by the spanning trees of the original -loop graph. Causality require…
