Spatially-Resolved Dynamics of the Amplitude Schmid-Higgs Mode in Disordered Superconductors

Author(s): P. A. Nosov, E. S. Andriyakhina, and I. S. Burmistrov We investigate the spatially-resolved dynamics of the collective amplitude Schmid-Higgs (SH) mode in disordered $s$-wave superconductors and fermionic superfluids. By analyzing the analytic structure of the zero-temperature SH susceptibility in the complex frequency plane, we find that, when the coh… [Phys. Rev. Lett. 135, 056001] Published Wed Jul 30, 2025
