Signatures of superconducting Higgs mode in irradiated Josephson junctions
Aritra Lahiri, Juan Carlos Cuevas, Björn Trauzettel
The Higgs mode, originally proposed in the context of superconductivity, corresponds to oscillations of the amplitude of the superconducting order parameter. Recent THz-domain opti…

From local to collective superconductivity in proximitized graphene
Stefano Trivini, Tim Kokkeler, Jon Ortuzar +8
The superconducting proximity effect induces pairing correlations in metallic systems via Andreev scattering. This effect is particularly intriguing in graphene, as it enables two-…
