    Detecting the vibrations of individual molecules directly in the mid-infrared regime is hindered by thermal noise. Here researchers bypass conventional detectors and upconvert the mid-infrared photons into visible light using molecular bonds, yielding an optical readout for single-molecule vibrational spectroscopy.

    Weak interaction of light with matter makes its tunable control notoriously challenging, resulting in bulky and inefficient devices. Now, a study demonstrates that van der Waals antiferromagnets featuring strong spin-charge induced anisotropy could offer excellent control of light polarization selectivity.
