Loops and loop clouds - a numerical approach to the worldline formalism in QED -
Holger Gies, Kurt Langfeld
A numerical technique for calculating effective actions of electromagnetic backgrounds is proposed, which is based on the string-inspired worldline formalism. As examples, we consi…
Gluon propagators and quark confinement
K. Langfeld, H. Reinhardt, J. Gattnar
The gluon propagator is investigated in Landau and in maximal center gauge for the gauge group SU(2) by means of lattice gauge simulations. We find that Gribov ambiguities arising…
Quantum diffusion of magnetic fields in a numerical worldline approach
Holger Gies, Kurt Langfeld
We propose a numerical technique for calculating effective actions of electromagnetic backgrounds based on the worldline formalism. As a conceptually simple example, we consider sc…
A picture of the Yang-Mills deconfinement transition and its lattice verification
M. Engelhardt, K. Langfeld, H. Reinhardt +1
In the framework of the center vortex picture of confinement, the nature of the deconfining phase transition is studied. Using recently developed techniques which allow to associat…
Quark Condensation, Induced Symmetry Breaking and Color Superconductivity at High Density
Kurt Langfeld, Mannque Rho
The phase structure of hadronic matter at high density relevant to the physics of compact stars and relativistic heavy-ion collisions is studied in a low-energy effective quark the…
Induced symmetry breaking and a new phase of hadronic matter at high density
Kurt Langfeld
The notion induced symmetry breaking (ISB) is introduced as a generalization of the spontaneous symmetry breaking mechanism and is illustrated in a simple two flavor spin model. In…
