Seamus Davis receives Investigator award from Gordon and Betty Moore Foundation

The Gordon and Betty Moore Foundation has selected nineteen Moore Experimental Investigators in Quantum Materials, including J.C. Seamus Davis. Through grants to 11 universities around the United States, this five-year, $34.2M investigator program will allow outstanding physicists to pursue ambitious, high-risk research, including the development of new experimental techniques.  Read more in the Moore Foundation press release.

Memorial Service for Dean Emeritus Geoffrey Chester Scheduled for 9/20

Geoffrey V. Chester, professor emeritus of physics and dean emeritus of Cornell’s College of Arts and Sciences, died June 27 at age 86 in Ithaca. A professor at Cornell since 1964, he was an authority on liquid helium. His research group was one of the first to carry out simulations of a wide range of condensed-matter systems. Much of his work focused on the liquid and solid phases of helium three and four. In addition he was interested in classical and quantum spin systems, order and disorder in solids, two-dimensional melting and problems in materials science. “Geoffrey Chester’s work pioneered the use of computational methods to elucidate the nature of the ground state of helium,” said Jeevak Parpia, professor and chair of physics. “He also was a willing member of many experimental Ph.D. students’ special committees (including mine) and was known and sought after for his deep insight.” A campus memorial service for Arts and Sciences Dean Emeritus Geoffrey Chester will be held Saturday, September 20 at 2 p.m. in Anabel Taylor Chapel.

Mellnik and Ralph pioneer use of spin torque in efficient computer memory

Alex Mellnik and Dan Ralph, in partnership with Nitin Samarth at Penn State, have a novel approach to computer memory they call a "topological insulator." Using the spin orientation of electrons their approach could lead to memory devices that are 10 times more efficient than any other known methods.
