    • Saturating field configurations for the massless thirring-wess model 

      Girotti, Horacio Oscar (1979) [Journal article]
      The saturation of the massless Thirring-Wess model by induced field configurations is presented. The limiting procedure connecting the massless Thirring-Wess model arith the Schwinger model is reexamined. Special emphasis ...
    • Saturation of the massive Schwinger model 

      Girotti, Horacio Oscar (1980) [Journal article]
      We determine the field configurations saturating the massive Schwinger model (MSM). Fermion confinement is proved, for the MSM, without invoking the Bose form of the theory. A gas of induced instantons accounts for the ...
