1. Integrability and Thermodynamics of the Gross-Neveu Model
University essay from KTH/FysikAbstract : The Gross-Neveu model is a quantum field theory of interacting N-flavor fermions in 1+1dimensions, with interaction term $(\bar{\psi}_f\psi_f )^2$. This model is studied using the property offactorized scattering. READ MORE

2. Calculating scattering amplitudes in φ3 and Yang-mills theory using perturbiner methods
University essay from Uppsala universitet/Teoretisk fysikAbstract : We calculate tree-level scattering amplitudes in φ^3 theory and Yang-Mills theory by means of the perturbiner expansion. This involves solving the Euler-Lagrange equations of motion perturbatively via a multi-particle ansatz, and using Berends-Giele recursion relations to extract the solution from simple on-shell data.

3. Updating bounds on the low-energy constants of Chiral Perturbation Theory from exact bounds on amplitudes
University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisationAbstract : Chiral perturbation theory is an efficient effective theory to describe meson-meson scattering at low energy. An effective theory naturally introduces low energy constants and they are used, for example, to solve the ultraviolet divergences. READ MORE
