A minimal model with stochastically broken reciprocity
Z. C. Tu
We introduce a minimal model consisting of a two-body system with stochastically broken reciprocity (i.e., random violation of Newton's third law) and then investigate its statisti…

Weighted average temperature as the effective temperature of a system in contact with two thermal baths
Z. C. Tu
We investigate the effective temperature of a harmonic chain whose two ends are coupled to two baths at different temperatures. We propose to take the weighted average temperature…
