Performance Boost of a Collective Qutrit Refrigerator
Dmytro Kolisnyk, Gernot Schaller
Abstract
One of the world's tiniest autonomous refrigerators can be realized by a single qutrit coupled to three thermal reservoirs. The authors analyze the performance of multiple collectively coupled qutrits, and observe a quantum boost in the steady-state cooling current with a quadratic scaling in the working fluid size. With additional interqutrit interactions, the quantum boost can be maintained also for larger systems and not perfectly collective scenarios, enabling efficient quantum cooling.
