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…
Local bosonic versus HMC --- a CPU cost comparison
Stephan Elser, Burkhard Bunk
We compare the CPU cost of HMC to various implementations of the Hermitean variant of Lüscher's local bosonic algorithm (LBA) for 2D massive QED with two flavours of Wilson fermion…
Two-flavour Schwinger model with dynamical fermions in the Lüscher formalism
Stephan Elser, Burkhard Bunk
We report preliminary results for 2D massive QED with two flavours of Wilson fermions, using the Hermitean variant of Lüscher's bosonization technique. The chiral condensate and me…
QED(1+1) at Finite Temperature -- a Study with Light-Cone Quantisation
Stephan Elser, Alex C. Kalloniatis
We explore quantum electrodynamics in (1+1) dimensions at finite temperature using the method of Discretized Light-Cone Quantisation. The partition function, energy and specific he…
