WebThe Higgs-mode propagator contains the fluctuation of the superconducting gap amplitude, which is diagrammatically shown in Fig. 5. Here the dotted lines represent the bare attractive... Web24 de abr. de 2024 · The Higgs mode has been detected in many different systems, including in ultracold atomic gases, disordered superconductors, and dimerized quantum magnets. However, in many cases, the Higgs mode is unstable and decays. As such, it has only been reported in a handful of publications.

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. WebHiggs mode are amplitude oscillations of a quantum field. Effective Lorentz symmetry is necessary.

WebIn this review, we discuss the theory and the possible observation of the amplitude or Higgs modes in condensed matter physics—in superconductors, cold atoms in periodic lattices, and uniaxial antiferromagnets. We discuss the necessity for at least approximate particle-hole symmetry as well as the special conditions required to couple to such ...
