Abstract:
The charge of subgap state in Andreev quantum dot (AQD) inserted into the superconducting loop is very sensitive to the magnetic flux threading the loop. We studied the sensitivity as a function of AQD parameters in details in $\Delta\to\infty$ limit. We also accounted for a weak Coulomb interaction in AQD. We discuss a possibility of using this setup as a device detecting week magnetic field.
