Magnetic Permeability of Confined Fermionic Vacuum
We obtain using Schwinger’s proper time approach the Casimir-Euler-Heisenberg effective action of fermion fluctuations for the case of an applied magnetic field between confining plates. Aside of higher order non-linear field effects we identify a novel contribution to the vacuum permeability. These contributions are exceedingly small for normal electromagnetism due to the smallness of the elec...
متن کاملMagnetic permeability of constrained scalar QED vacuum
We compute the influence of boundary conditions on the Euler-Heisenberg effective Lagrangian scalar QED scalar for the case of a pure magnetic field. The boundary conditions constrain the quantum scalar field to vanish on two parallel planes separeted by a distance a and the magnetic field is assumed to be constant, uniform and perpendicular to the planes. The effective Lagrangian is obtained u...
متن کاملMagnetic Permeability in Constrained Fermionic Vacuum
We obtain using Schwinger’s proper time approach the Casimir-Euler-Heisenberg effective action of fermion fluctuations for the case of an applied magnetic field. We implement here the compactification of one space dimension into a circle through anti-periodic boundary condition. Aside of higher order non-linear field effects we identify a novel contribution to the vacuum permeability. These con...
متن کاملColor Magnetic Flux Tubes in Dense QCD
QCD is expected to be in the color-flavor locking phase in high baryon density, which exhibits color superconductivity. The most fundamental topological objects in the color superconductor are non-Abelian vortices which are topologically stable color magnetic flux tubes. We present numerical solutions of the color magnetic flux tube for diverse choices of the coupling constants. We also analyti...
متن کاملNonperturbative dynamics in the colour – magnetic QCD vacuum
In the deconfinement phase of QCD quarks and gluons interact with the dense stochastic colour–magnetic vacuum. We consider the dynamics of quarks in this deconfinement phase using the Field Correlators Method and derive an effective nonperturbative interquark potential, in addition to the usual perturbative short–ranged interaction. We find the resulting angular–momentum–dependent interaction t...
