Higgs Spectroscopy and Control of Non-Equilibrium Phases in Superconductors by Terahertz Light-Induced Supercurrent Injection

摘要

The non-equilibrium dynamics of superconductors after ultrafast terahertz excitation is analyzed. Excitation of selective non-equilibrium phases and detection of Higgs mode in the nonlinear response are demonstrated by inducing supercurrents via terahertz pulse shaping.
