Approaching the perfect diode limit through a nonlinear interface
Approaching the perfect diode limit through a nonlinear interface
We consider a system formed by two different segments of particles, coupled to thermal baths, one at each end, modeled by Langevin thermostats. The particles in each segment interact harmonically and are subject to an on-site potential for which three different types are considered, namely, harmonic, ${\ensuremath{\phi}}^{4}$, and Frenkel-Kontorova. The …
