Develops a next-generation scanning nano-SQUID-on-tip (SOT) microscope optimized for operation inside a dilution refrigerator, enabling magnetic and thermal imaging down to millikelvin temperatures. By integrating sub-100-nm SQUID sensors at the apex of a pulled quartz tip, to achieve simultaneous nanometer-scale spatial resolution and high magnetic flux sensitivity. This platform opens new avenues for probing emergent quantum phases—such as unconventional superconductors, topologically non-trivial materials, and hybrid superconductor–ferromagnet interfaces—whose signatures often vanish above 1 K.
