Landau gauge
TīmeklisThe propagator for the gauge field is different depending on the choice of gauge. The choice of Landau gauge forces $\partial_\mu A^\mu=0$, but I have never seen a similiar statement for the other gauges. I would like to know what constraint on the gauge field is produced by the other covariant gauges. Tīmeklis2024. gada 12. jūl. · A longstanding question in QCD is the origin of the mass gap in the Yang-Mills sector of QCD, i.e., QCD without quarks. In Landau gauge QCD this mass gap, and hence confinement, is encoded in a mass gap of the gluon propagator, which is found both in lattice simulations and with functional approaches. While functional …

HΓ + k = kxσx + kyσy + (Δ + 2)σz. For the Hamiltonian H(k) = kxσx + kyσy + mσz, we can get the monopole field for E − state is.
