Higgs Mode (IMAGE) The University of Hong Kong Caption Graph 3. Frequency dependence of the spectrum of the Higgs mode (b) and the scalar mode (a) evolve with the dimension reduction. In this dimensional reduction, a sharp peak is emerging, which means the signal of the scalar mode and the Higgs mode becomes stronger.
