SQCRAMscope

The SQCRAMscope (Scanning Quantum Cryogenic Atom Microscope) uses an ultracold quantum gas as a micron-resolution magnetometer. It is capable of imaging DC electron transport and magnetization in both room-temperature and cryogenically cooled quantum materials with unprecedented sensitivity. This novel microscope was the first example of the direct marriage of ultracold AMO physics with condensed matter physics for the exploration of technologically relevant strongly correlated and topologically nontrivial materials. For example, we used the SQCRAMscope to locally image the electron nematic domains that arise in an iron-pnictide high-T_c superconductor.
