Theory of the Photonic Joule Effect in Superconducting Circuits

Author(s): Samuel Cailleaux, Quentin Ficheux, Nicolas Roch, and Denis M. Basko When a small system is coupled to a bath, it is generally assumed that the state of the bath remains unaffected by the system due to the bath’s large number of degrees of freedom. Here, we show theoretically that this assumption can be easily violated for photonic baths typically used in experiments… [Phys. Rev. Lett. 134, 227001] Published Wed Jun 04, 2025
