In this lecture, I will present our calculations of this linear microwave response, with special emphasis on spinful (odd occupied) quantum dots giving rise to Yu-Shiba-Rusinov bound states and the accompanying interaction driven quantum phase transition from \u03c0- to 0-junction behavior. I shall also discuss the intricate dc current response of a Josephson junction based on a double quantum dot with two phase shifted microwave tones on the individual gate voltages. This is shown to lead to a tunable phi_0 junction and to allow for supercurrent rectification.<\/p>\n<p>YouTube link: <a href=\"https:\/\/www.youtube.com\/watch?v=gFviD0Ktypc\">https:\/\/www.youtube.com\/watch?v=gFviD0Ktypc<\/a><\/p>\n<p style=\"text-align: left\">[1] Cecilie Hermansen, Alfredo Levy Yeyati, JP, Phys.
