The Spectrum of QED in the framework of the DLCQ method
Stephan Elser
We investigate the influence of the fermion field boundary conditions on the spectrum and wavefunctions of QED in the Discretized Light-Cone Quantization formalism suggeste…
The Local Bosonic Algorithm applied to the massive Schwinger model
Stephan Elser
We investigate various variants of the Hermitean version of the Local Bosonic Algorithm proposed by M. Lüscher. The model used is two-dimensional Quantum Electrodynamics (QED) with…
Topological sectors and the pion mass
Stephan Elser, Burkhard Bunk
We study quenched and dynamical pion correlators in the two-flavour Schwinger model (2D QED) both within topological charge sectors and averaged. The results show that a clean-cut…
Discretized Light-Cone Quantization: Solving a 1+1 dimensional field theory (QED)
Stephan Elser, Hans-Christian Pauli, Alex C. Kalloniatis
We describe the programming method for generating the spectrum of bound states for relativistic quantum field theories using the nonperturbative Hamiltonian approach of Discretized…
