Quantum thermodynamic uncertainty relation and macroscopic superconducting coherence
Franco Mayo, Nahual Sobrino, Rosario Fazio +2
Stability and efficiency are mutually exclusive in a thermodynamic process, e.g. in a thermal machine. Any effort to reduce the fluctuations of a certain output quantity is necessa…
Finite-time thermal refrigerator in interacting Bose-Einstein Condensates
JoaquÃn I. Ganly, Julián Amette Estrada, Franco Mayo +2
We study a finite-time thermodynamic refrigeration cycle realized numerically in three-dimensional, weakly interacting Bose-Einstein condensates (BECs). The setup consists of three…
Purcell Enhancement and Suppression in Laser Cooling of Yb:YLF Nanocrystals in a Fabry-Pérot Microcavity
Lucas Mendicino, Franco Mayo, Christian Schmiegelow +1
We investigate the improvement of anti-Stokes laser cooling of a Yb:YLF nanocrystal in a Fabry-Pérot microcavity via the Purcell effect. Our analysis accounts for both the…
Enhancing the efficiency of quantum measurement-based engines with entangling measurements
Franco Mayo, Augusto J. Roncaglia
We study the impact of entangling measurements on the efficiency of quantum measurement- based engines. We first show that for engines comprising many subsystems their efficiency c…
