Magnetic sensing

We use superconducting levitation of macroscopic mirrors to study optomechanics of magnetic levitation and its application in magnetic and radiation pressure sensing.

Temperature sensing in live cells

In collaboration with Dr. Amir Hajrasouliha at IU Health, we used nanodiomonds (ND) hosting nitrogen vacancy centers (NVs) as a probe of temperature inside live cells. The optical detection of magnetic resonance (ODMR) enables determination of a shift in the NV spin transition induced by change in the temperature around the ND. The approach enables precise determination of temeprature in live cells with high spatial resolution.
