COOLING BY HEATING: REFRIGERATION POWERED BY PHOTONS

"Cooling by Heating: Refrigeration Powered by Photons". B. Cleuren, B. Rutten, C. Van den Broeck. PHYSICAL REVIEW LETTERS 108, 120603 (2012). DOI: 10.1103/PhysRevLett.108.120603

 We propose a new mechanism for refrigeration powered by photons. We identify the strong coupling regime for which maximum efficiency is achieved. In this case, the cooling flux is proportional to T in the low temperature limit T→0.

Se propone un mecanismo nuevo para la refrigeración propiciada por fotones. Se identificó el régimen de acoplamiento fuerte para el cual se alcanza la máxima eficiencia. En este caso, el flujo de enfriamiento es proporcional a la temperatura T en el límite de bajas temperaturas T→0.
