Stationary currents in long-range interacting magnetic systems
Roberto Boccagna
We construct a solution for the integro-differential stationary equation derived from a finite-volume version of the mesoscopic model proposed in [G. B. Giacomin, J. L. Lebowi…

Current with "wrong" sign and phase transitions
Roberto Boccagna
We prove that under certain conditions, phase separation is enough to sustain a regime in which current flows along the concentration gradient, a phenomenon which is known in the l…
