Terahertz radiation could shed more light on collective excitations in unconventional superconductors
Developing a practical room-temperature superconductor is the holy grail of condensed matter physics. In addition to their plethora of potential applications, superconductors present a playground for future single-chip terahertz technologies. Near-field terahertz imaging could offer new insight into superconducting nonlinear excitations: terahertz radiation represents a peculiar energy scale of important condensed matter excitations, which renders them an indispensable probe for electron–electron coupling mechanisms in unconventional correlated systems. Funded by the Marie Skłodowska-Curie Actions programme, the SUPERTERA project plans to apply near-field imaging techniques to investigate the terahertz responses of certain superconducting systems at the nanoscale, such as high-temperature superconducting layered cuprates and twisted bilayer graphene.
