Can quantum gases be used as direct probes of condensed matter systems? If, so what sensing advantage might they provide? Our group has recently developed the SQCRAMscope (Scanning Quantum Cryogenic Atom Microscope), a novel quantum sensor that 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. Our novel microscope opens a new frontier in quantum metrology and is 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 have already used the SQCRAMscope to locally imagine the electron nematic domains that arise in an iron-pnictide high-Tc superconductor.
