Large-Field Vacuum Decay in General Multi-Scalar Theories
Giorgio Busoni, Florian Goertz, Navneet Krishnan +1
Many theories beyond the standard model exhibit multiple scalar particles. Such multi-scalar theories can in principle host lower-energy vacua, and thus predict that our universe h…

Analytic formulae for non-local magic in bipartite systems of qutrits and ququints
Giorgio Busoni, John Gargalionis, Ewan N. V. Wallace +1
We conjecture analytic expressions for the non-local magic of bipartite pure qudit states of prime local dimension. Our construction relies on the Schmidt-aligned state attaining t…

Emergent symmetry in a two-Higgs-doublet model from quantum information and nonstabiliserness
Giorgio Busoni, John Gargalionis, Ewan N. V. Wallace +1
Studies of scattering processes in scalar models with two Higgs doublets have recently hinted at a connection between the absence of flavour-space entanglement in scatteri…
