Fermions and Condensates on the Light-Front
M. Burkardt
Light-Front quantization is one of the most promising and physical tools towards studying deep inelastic scattering on the basis of quark gluon degrees of freedom. The simplified v…
On the calculation of hadron form factors from Euclidean Dyson-Schwinger equations
M. Burkardt, M. R. Frank, K. L. Mitchell
We apply Euclidean time methods to phenomenological Dyson-Schwinger models of hadrons. By performing a Fourier transform of the momentum space correlation function to Euclidean tim…
A 3+1 Dimensional Light-Front Model with Spontaneous Breaking of Chiral Symmetry
M. Burkardt, H. El-Khozondar
We investigate a 3+1 dimensional toy model that exhibits spontaneous breakdown of chiral symmetry, both in a light-front (LF) Hamiltonian and in a Euclidean Schwinger-Dyson (SD) fo…
Confinement and Light-Front QCD
Matthias Burkardt
Numerical results for the (rest-frame) potential in light-front quantized on a lattice are presented. Both in the longitudinal as well as the …
Confinement in Light-Front QCD
Matthias Burkardt
Numerical results for the calculation of the (rest-frame) potential, for light-front quantized on a lattice are presented. Both in the longitudinal a…
Background-Field Formalism in Quantum Systems
Matthias Burkardt, Derek B. Leinweber, Xuemin Jin
The background-field formalism is used extensively in fundamental approaches to QCD to explore hadronic matrix elements of various currents. While the lattice QCD approach is formu…
