Landau and cluster structures of one-loop amplitudes in SYM in dimensional regularization
Athanasia-Konstantina Angelopoulou, Ruth Britto, Matteo Parisi
Generalized unitarity, Landau analysis, and cluster adjacency encode complementary aspects of scattering amplitudes. We use one-loop planar SYM amplitudes in dimensi…
Interplay between photon condensation and electron-electron interactions in molecular systems
Matteo Parisi, Elisabetta Paladino, Giuseppe A. Falci +4
We investigate a minimal molecular model consisting of square planar plaquettes hosting multiple electrons, whose dynamics is governed by a tight-binding Hamiltonian supplemented b…
Positivity and Cluster Structures in Landau Analysis
Benjamin Hollering, Elia Mazzucchelli, Matteo Parisi +1
Landau analysis in momentum twistor space can be formulated as the study of varieties of lines in three-dimensional projective space, together with their projections and discrimina…
Landau Analysis in the Grassmannian
Benjamin Hollering, Elia Mazzucchelli, Matteo Parisi +1
Momentum twistors for scattering amplitudes in particle physics are lines in three-space. We develop Landau analysis for Feynman integrals in this setting. The resulting discrimina…
