DMRG study of the theta-dependent mass spectrum in the 2-flavor Schwinger model
Abstract We study the θ-dependent mass spectrum of the massive 2-flavor Schwinger model in the Hamiltonian formalism using the density-matrix renormalization group (DMRG). The masses of the composite particles, the pion and sigma meson, are computed by two independent methods. One is the improved on...
