SQCRAMscope microscopy

SQCRAMscope microscopy

Microscopy techniques co-opted from nonlinear optics and high energy physics have complemented solid-state probes in elucidating exotic order manifest in condensed matter materials.  Up until now, however, no attempts have been made to use modern techniques of ultracold atomic physics to directly explore properties of strongly correlated or topologically protected materials.  

We introduce the SQCRAMscope, a novel Scanning Quantum CRyogenic Atom Microscope technique for imaging magnetic fields arising from domain structure or electron transport near cryogenically cooled materials.  With our SQCRAMscope, we aim to image inhomogeneous transport and domain percolation in technologically relevant materials whose order has evaded elucidation.  Our current projects include imaging transport in unconventional superconductors and topologically non-trivial materials.
