The Higgs mode's resonance frequency lies near 2*Delta, where its contribution to the complex conductivity is at its maximum. In contrast, at much lower frequencies (<<2*Delta), this contribution rapidly diminishes. However, could the Higgs mode's contribution still be fundamentally significant in this low-frequency regime, which is crucial for superconducting devices? This study aims to clarify this question.
