Asymmetric higher-harmonic SQUID as a Josephson diode
Asymmetric higher-harmonic SQUID as a Josephson diode
We theoretically investigate asymmetric two-junction SQUIDs with different current-phase relations in the two Josephson junctions, involving higher Josephson harmonics. Our main focus is on the ``minimal model'' with one junction in the SQUID loop possessing the sinusoidal current-phase relation and the other one featuring additional second harmonic. The current-voltage characteristic …
