The paper “Scattering amplitude recursion relations in BV quantisable theories“, co-authored by Tommaso Macrelli, Christian Saemann (Heriot-Watt University), and Martin Wolf, has been published in Physical Review D. Tree-level scattering amplitudes in Yang-Mills theory satisfy a recursion relation due to Berends and Giele which yields the famous Parke-Taylor formula for MHV amplitudes. The paper shows […]

The paper “Koopman wavefunctions and classical-quantum correlation dynamics” co-authored by Denys I. Bondar (Tulane University), François Gay-Balmaz (Ecole Normale Sup, Paris), and Cesare Tronci has been accepted for publication in the Proceedings A of the Royal Society of London. The paper addresses the long-standing problem of formulating a dynamical theory of classical-quantum coupling. The figure […]
