A general framework for the description of classic wave propagation is introduced. This relies on a cone structure C determined by an intrinsic space ? velocities (point, direction and time-dependent) observers’ vector field ???t whose integral curves provide both Zermelo problem auxiliary Lorentz–Finsler metric G compatible with C. The PDE wavefront reduced to ODE t-parametrized geodesics Part...

We investigate the dissipative loss in the ±J Ising spin glass in three dimensions through the scaling of the hysteresis area, for a maximum magnetic field that is equal to the saturation field. We perform a systematic analysis for the whole range of the bond randomness as a function of the sweep rate by means of frustration-preserving hard-spin mean-field theory. Data collapse within the entir...

The one-loop contribution to the polarization operator of charged gluons in a constant Abelian chromomagnetic field at high temperature is calculated. By averaging the operator over the physical states of the transversal gluons in the field the temperature-dependent radiation corrections to the gluon energy spectrum are obtained for the high-temperature limit, gH c T 2 ≪ 1. It is found, in part...
