Probing and manipulating the superconducting state of NbSe2 in the 2D limit

Jun 22, 2024 | PostDoc

Context:. The dynamics of superconductors (SC) driven out-of-equilibrium is governed by their collective mode spectrum, and in particular the SC amplitude mode which is an analog of the Higgs mode in high-energy physics [1]. In many materials the coexistence of SC...

2D TMD embedded in a THz split ring cavity (left) The resulting coupled light-SC matter state is probed by Raman and THz spectroscopy. The SC Higgs mode is a collective oscillation of the SC condensate (right) that can couple to cavity photon to form cavity-Higgs...
