1. 1. Integrability and Thermodynamics of the Gross-Neveu Model

   Master-uppsats, KTH/Fysik

   Författare :Valdemar Melin; [2023]
   Nyckelord :Mathematical Physics; Quantum Field Theory; Bethe Ansatz; Gross-Neveu Model; Matematisk fysik; kvantfältteori; Bethe-ansatsen; Gross-Neveu-modellen;

   Sammanfattning : 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. LÄS MER

3. 2. Quantum Mechanical Propagators Related to Classical Orthogonal Polynomials

   Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

   Författare :Valdemar Melin; [2021]
   Nyckelord :;

   Sammanfattning : A few quantum systems on the line with weighted classical orthogonal polynomials as eigenstates are studied. Explicit expressions of the propagators,i.e. the integral kernels of the time evolution operators, are derived. LÄS MER
