Higgs mode in superconductors
WebOne important consequence of the distinction between true symmetries and gauge symmetries, is that the massless Nambu–Goldstone resulting from spontaneous breaking of a gauge symmetry are absorbed in the description of the gauge vector field, providing massive vector field modes, like the plasma mode in a superconductor, or the Higgs … Web• Nonlinear terahertz generation from the Higgs mode in high-Tc superconductors (published in Nature Communications) • Terahertz …
