Higgs mode in superconductors
Web5 de jul. de 2016 · We consider the amplitude (Higgs) mode in a superconductor with a condensate flow (supercurrent). We demonstrate that, in this case, the amplitude mode corresponding to oscillations of the superconducting gap is excited by an external ac electric field already in the first order in , so that , where is the velocity of the condensate.
