Our laboratory is outfitted with a dry dilution refrigerator cryostat which has a base temperature of <10 mK and an out-of-plane magnetic field of ≤9 T. The cryostat is outfitted with active vibration isolation stages and a fast-loading mechanism to enable noise-sensitive measurements and fast turn-around times. This cryostat is our central experimental platform to implement novel quantum sensing microscopies.

Currently, we are implementing scanning microwave impedance microscopy (1) and quantum twisting microscopy (2). These methods will serve as a stepping stone to implement more advanced microwave-based scanning probe techniques, such as scanning qubit microscopy (3). To this end, we develop our own measurement modules and nanopositioning stages, which will be suited to conduct scanning probe microscopy measurements at lowest possible electron temperatures.

The goal of theses measurements will be to examine  the nature of topologically non-trivial many body states, correlated insulators, and unconventional superconductivity appearing in two-dimensional moiré materials.
