On the possibility of magnetic flux detection by Andreev quantum dot
PACS: 73.21.La, 74.45.+c, 07.55.Ge
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 Δ → ∞ 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.
