Unveiling Hidden Properties of Quantum Materials with Ultrafast Laser Probing
Researchers at the University of California San Diego have used an advanced optical technique to uncover hidden properties of a quantum material called Ta2NiSe5 (TNS). By shining a laser on the material, they were able to observe anomalous terahertz light amplification, revealing some of the hidden properties of the TNS exciton condensate. This work could have implications in the emerging field of entangled light sources utilizing quantum materials.
