This highlight focuses on the development of new thermometry required to study quantum materials and phenomena in high magnetic fields and at ultralow temperatures. The team has demonstrated that exceedingly small quartz tuning forks bathed in liquid 3He maintain a constant calibration that is magnetic field independent, thereby opening the use of these devices as new sensors of the response of quantum systems.

This highlight reports on the still poorly understood transition to an electron crystalline state (the Wigner crystal) in a two-dimensional system at extremely low densities, observable at low temperatures as a function of magnetic field. This experiment finds a surprising stabilization of the Wigner crystal arising from magnetic-field-induced spin alignment. Such electrically-delicate samples require the ultra-low-noise environment and experimental techniques available at the High B/T facility.

Study of helium atoms at low temperatures illuminate extreme quantum effects that were earlier predicted.

Scientists found that the emergence of an exotic quantum mechanical phase in Ce1-xNdxCoIn5 is due to a shape change in the Fermi surface. This finding ran counter to theoretical arguments and has led investigators in new directions.

This research established experimental evidence for the long sought-after transition of a small, two-dimensional sheet of electrons to a solid state.

New materials that exhibit a strong coupling between magnetic and electric effects are of great interest for the development of high-sensitivity detectors and other devices. This paper reports on such a coupling in a specially designed material.

Experiment shows that emergent quantum fluid behavior of helium-3 confined to one dimension is observable using special low-temperature NMR techniques.

Observing growth processes in classical alloys is extremely difficult; scientists overcame this by studying quantum systems.

At high magnetic field, free-flowing particles condense into “puddles.”

Controlled by electron interactions, the Mott transition is accompanied by a reduction in the volume of the atomic lattice.
