Scattering Amplitudes from Intersection Theory
Sebastian Mizera
We use Picard-Lefschetz theory to prove a new formula for intersection numbers of twisted cocycles associated to a given arrangement of hyperplanes. In a special case when this arr…
Renormalization of tensor networks using graph independent local truncations
Markus Hauru, Clement Delcamp, Sebastian Mizera
We introduce an efficient algorithm for reducing bond dimensions in an arbitrary tensor network without changing its geometry. The method is based on a novel, quantitative understa…
Combinatorics and Topology of Kawai-Lewellen-Tye Relations
Sebastian Mizera
We revisit the relations between open and closed string scattering amplitudes discovered by Kawai, Lewellen, and Tye (KLT). We show that they emerge from the underlying algebro-top…
A String Deformation of the Parke-Taylor Factor
Sebastian Mizera, Guojun Zhang
Scattering amplitudes in a range of quantum field theories can be computed using the Cachazo-He-Yuan (CHY) formalism. In theories with colour ordering, the key ingredient is the so…
Echoes of Asymptotic Silence in Causal Set Quantum Gravity
Astrid Eichhorn, Sebastian Mizera, Sumati Surya
We explore the idea of asymptotic silence in causal set theory and find that causal sets approximated by continuum spacetimes exhibit behaviour akin to asymptotic silence. We make…
Can scalars have asymptotic symmetries?
Miguel Campiglia, Leonardo Coito, Sebastian Mizera
Recently it has been understood that certain soft factorization theorems for scattering amplitudes can be written as Ward identities of new asymptotic symmetries. This relationship…
