An Algebraic Obstruction to Ising Criticality for Finite-BCH Entanglers in Wavelet MERA
Enrico Bertuzzo, Olindo Corradini, Claudia Frugiuele
The computational treatment of non-Gaussian entanglers could pose a significant challenge when extending the Multi-Scale Entanglement Renormalization Ansatz (MERA) to interacting q…
Gluon amplitudes in first quantization
Fiorenzo Bastianelli, Roberto Bonezzi, Olindo Corradini +1
We compute tree-level gluon amplitudes as worldline correlators of vertex operators in a bosonic spinning particle model. In this framework, the particle's position degrees of free…
Obtaining fully polarised amplitudes in gauge invariant form
Naser Ahmadiniaz, Victor Miguel Banda Guzman, Christian Schubert +3
We describe progress applying the \textit{Worldline Formalism} of quantum field theory to the fermion propagator dressed by -photons to study multi-linear Compton scattering pro…
Manifest colour-kinematics duality and double-copy in the string-based formalism
Naser Ahmadiniaz, Filippo Maria Balli, Olindo Corradini +3
The relation for the gravity polarisation tensor as the tensor product of two gluon polarisation vectors has been well-known for a long time, but a version of this relation for mul…
Dimensional Regularization for the Particle Transition Amplitude in Curved Space
Olindo Corradini, Luigi Crispo, Maurizio Muratori
We compute the perturbative short-time expansion for the transition amplitude of a particle in curved space time, by employing Dimensional Regularization (DR) to treat the divergen…
Worldline master formulas for the dressed electron propagator, part 2: On-shell amplitudes
Naser Ahmadiniaz, Victor Miguel Banda Guzman, Fiorenzo Bastianelli +3
In the first part of this series, we employed the second-order formalism and the ``symbol'' map to construct a particle path-integral representation of the electron propagator in a…
