A cryogenic apparatus for coupling two-dimensional materials to a confocal multimode optical cavity
A cryogenic system was developed to link two-dimensional materials to a confocal optical cavity for studying correlated electron physics. This setup allows for in situ imaging, electrical transport measurements, and driving steady-state phonon populations using cavity-enhanced Raman transitions. The apparatus achieves high stability at 10.4 K while enabling precise sample manipulation and coherent light-matter coupling.
