Cette courte revue présente le domaine émergent de la physique mésoscopique avec les atomes froids, et met l'accent sur le transport thermique et « thermoélectrique », c'est-à-dire le transport couplé de particules et d'entropie. Nous comparons notamment des prédictions théoriques à des observations expérimentales d'effets thermoélectriques au sein de ces systèmes. Nous montrons aussi comment la combinaison de propriétés de transport bien adaptées et du refroidissement évaporatif conduit à l'équivalent d'un effet Peltier pour atomes froids, pouvant fournir une nouvelle méthode de refroidissement présentant un rendement et une puissance améliorés en comparaison du refroidissement évaporatif usuellement utilisé dans les gaz d'atomes froids. Ceci pourrait conduire à une nouvelle génération d'expériences permettant de sonder les effets de corrélations fortes dans les gaz d'atomes fermioniques ultra-froids aux basses températures.
This brief review presents the emerging field of mesoscopic physics with cold atoms, with an emphasis on thermal and ‘thermoelectric’ transport, i.e. coupled transport of particles and entropy. We review in particular the comparison between theoretically predicted and experimentally observed thermoelectric effects in such systems. We also show how combining well-designed transport properties and evaporative cooling leads to an equivalent of the Peltier effect with cold atoms, which can be used as a new cooling procedure with improved cooling power and efficiency compared to the evaporative cooling currently used in atomic gases. This could lead to a new generation of experiments probing strong correlation effects of ultracold fermionic atoms at low temperatures.
