    Keywords : Mathematical Physics; Quantum Field Theory; Bethe Ansatz; Gross-Neveu Model; Matematisk fysik; kvantfältteori; Bethe-ansatsen; Gross-Neveu-modellen;

    Abstract : 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

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

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Valdemar Melin; [2021]
    Keywords : ;

    Abstract : 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. READ MORE
