Tīmeklis2024. gada 17. jūl. · The Landau Gauge raintrek Jan 3, 2008 Jan 3, 2008 #1 raintrek 75 0 Could anybody explain to me the difference between a Landau Gauge and Symmetric Gauge? I know the Landau Gauge is given by A = (0,Bx,0) producing a constant magnetic field in the z direction. TīmeklisIn physics, the Landau pole (or the Moscow zero, or the Landau ghost) is the momentum (or energy) scale at which the coupling constant (interaction strength) of a quantum field theory becomes infinite. Such a possibility was pointed out by the physicist Lev Landau and his colleagues. The fact that couplings depend on the momentum … first watch lavender drink
