| Sumario: | We study heat rectification using a minimalistic model of two different atoms trapped in harmonic potentials, where the atoms are subjected to effective Lan-gevin baths created by the Doppler cooling, while they interact by linear forces. We obtain analytical expressions for the steady state. If the exchange of baths is done changing temperature and friction coefficients at the same time an asymmetry of heat current is found. We also search for the highest asymmetry in the parameter space of the system.; Bero-errektifikazioa aztertzen dugu harrapatutako bi atomo ezberdi-nez osatutako modelo minimalista baten bidez. Atomoek indar linealak jasaten dituzte laserren bidez sorturiko Langevin bainu efektiboekin kontaktuan, Doppler efektuaren bidez sortuak. Egoera egonkorreko korronteen adierazpen analitikoak lortzen ditugu. Sistema lineal honetan bero-korronte asimetrikoa lortzen da bainuen tenperatura eta bainuek sistemarekiko duten akoplamendua aldi berean trukatzen badira. Modelo honen parametro- espazioa ere aztertzen dugu bero-korronte asimetria maximizatzeko. |
