Microwave irradiation of asymmetric transparent Josephson junctions produces resonant enhancement of the second harmonic in both the equilibrium current-phase relation and the AC Josephson current, with sign and frequency dependence that differ from standard expectations and thereby reveal the Higgs
Relative to this reference level, in the presence of a potentialV, the ground state withN+ 2 particles is lower in energy by 2eV

Signatures of superconducting Higgs mode in irradiated Josephson junctions
