Press release on two recent quantum ordering papers

Manipulating Quantum Order

Cool a material to sufficiently low temperatures and it will seek some form of collective order. Add quantum mechanics or confine the geometry and the states of matter that emerge can be exotic, including electrons whose spins arrange themselves in spirals, pinwheels, or crystals.

In a recent pair of publications in Nature Communications, teams led by Caltech's Thomas F. Rosenbaum, professor of physics and holder of the Sonja and William Davidow Presidential Chair, report how they have combined magnetic fields and large pressures to not only induce these states at ultra-low temperatures, but also to nudge them between competing types of quantum order.

We moved from Chicago. 2 semi trailers filled with equipment and other stuff. A crane lowered it all down into the Sloan subbasement. It took a week to unload.
