Resumen:
A transmission line coupled to an externally driven superconducting quantum interference device(SQUID) can exhibit the Dynamical Casimir Effect (DCE). Employing this setup, we quantize theSQUID degrees of freedom and show that it gives rise to a three-body interaction Hamiltonian withthe cavity modes. By considering only two interacting modes from the cavities we show that thedevice can function as an autonomous cooler where the SQUID can be used as a work source tocool down the cavity modes. Moreover, this setup allows for coupling to all modes existing insidethe cavities, and we show that by adding two other extra modes to the interaction with the SQUIDthe cooling effect can be enhanced.
