Project description
New spectroscopy method could unearth the fundamental mechanisms of superconductivity
Superconductivity, current transport without resistance, is one of the most exciting phenomena in modern solid-state physics. The EU-funded T-Higgs project will develop a new method, Higgs spectroscopy, to gain new insight into superconductivity dynamics. The method could allow to determine and classify the superconducting wave function, also known as the order parameter. The order parameter will be measured by determining the amplitude and phase of the Higgs oscillations. Classification of the order parameter – in particular, the non-trivial symmetries of unconventional superconductors – is important for understanding superconductivity mechanisms.
Objective
T-Higgs develops “Higgs Spectroscopy” as novel tool to probe the order parameter in superconductors. It will allow unprecedented insights into the structure and dynamics of the condensate and shine new light onto the physics of unconventional superconductors. In particular high temperature superconductivity calls for new probes to reveal its pairing mechanism. T-Higgs can also be applied to intriguing phenomena like light- induced superconductivity, superconductivity in “twisttronics” or under extreme conditions matching the ongoing importance of superconductivity in quantum materials.
T-Higgs is a high-field phase-resolved non-linear THz spectroscopy on order parameter excitations of the superconducting ground state itself, the Higgs oscillations. Probing the internal structure of the condensed Cooper pairs this reveals not only the symmetry of the order parameter but also couplings of the condensate to external modes and their interplay with superconductivity.
