The future of technology relies, to a great extent, on new materials, but the work of developing those materials begins years before any specific application for them is known. Stephen Wilson, a professor of materials in UC Santa Barbara's College of Engineering, works in that "long before" realm, seeking to create new materials that exhibit desirable new states.

In the paper "Field-tunable quantum disordered ground state in the triangular-lattice antiferromagnet NaYbO2," published in the journal Nature Physics, Wilson and colleagues Leon Balents, of the campus's Kavli Institute for Theoretical Physics, and Mark Sherwin, a professor in the Department of Physics, describe their discovery of a long-sought "quantum spin liquid state" in the material NaYbO2 (sodium ytterbium oxide). The study was led by materials student Mitchell Bordelon and also involved physics students Chunxiao Liu, Marzieh Kavand and Yuanqi Lyu, and undergraduate chemistry student Lorenzo Posthuma, as well as collaborators at Boston College and at the U.S. National Institute of Standards and Technology.
