Overview of the electronic band structure of TiSe2 in equilibrium and after excitation.

The elements in the periodic table are divided into metals, semimetals and non-metals. The distinction is based on their chemical and physical properties and is determined, in particular, by the movement of electrons and the materials' ability to conduct electrical energy: metals are excellent conductors, semimetals have...

The Joe Orenstein Group has published their findings on antiferromagnetic spin wavepackets in Nature Physics.

The spin of the electron is Nature’s perfect quantum bit, capable of extending the range of information storage beyond “one” or “zero.” Consequently, exploiting the electron...

Frances Hellman

Professor Emeritus of the Graduate School

Frances Hellman received her BA in Physics from Dartmouth College in 1978, graduating summa cum laude and phi beta kappa with high honors in physics. She received her PhD in Applied Physics from Stanford University in 1985, studying what were then considered the high Tc superconductors (the A15's). After a 2 year postdoc in thin film magnetism at AT&T Bell Labs, she went to UCSD as an assistant professor in 1987, where she received tenure in 1994 and became a full professor in 2000. She joined the Physics Dept at UC Berkeley in Jan 2005, and became Chair of the Department in 2007. She...

Robert Birgeneau

Arnold and Barbara Silverman Distinguished Professor of Physics, Materials Science and Engineering, and Public Policy, Chancellor Emeritus

Professor Birgeneau received his Ph.D. in Physics from Yale University in 1966 with Professor Werner Wolf. He was on the faculty of Yale for one year and then spent one year at Oxford University. He was at Bell Laboratories from 1968 to 1975 and then went to MIT in September 1975 as Professor of Physics. In 1988 he became head of the department and in 1991 became Dean of Science at MIT. In 2000, he became President of the University of Toronto. In 2004 he became UC Berkeley’s Chancellor and joined the Physics faculty. He concluded his service as Chancellor at the end of May 2013 and is now...
