Transmission of a microwave cavity coupled to localized Shiba states
Transmission of a microwave cavity coupled to localized Shiba states
We consider a strongly correlated quantum dot, tunnel coupled to two superconducting leads and capacitively coupled to a single mode microwave cavity. When the superconducting gap is the largest energy scale, multiple Shiba states are formed inside the gap. The competition of these states for the ground state signals a …
