Evidence for high-energy extraterrestrial neutrinos at the IceCube detector ushers in 'new age of astronomy'

November 21, 2013 - Neutrinos can zip right through your body, the walls of your house, entire planets, even emerging from near the surface of fascinating and frightening black holes. And now, an international scientific collaboration that includes researchers from the University of Delaware has taken an astronomical step forward in unmasking the origins of some of these high-energy particles, the so-called “messengers of the universe.”

Researchers using data from the IceCube Neutrino Observatory at the South Pole reveal new information about the origin of cosmic rays

August 29, 2013 - The origin of cosmic rays in the universe has confounded scientists for decades. But a study by researchers using data from the IceCube Neutrino Observatory at the South Pole reveals new information that may help unravel the longstanding mystery of exactly how and where these “rays” (they are actually high-energy particles) are produced.

NASA telescope provides insights into unusual dwarf star

June 14, 2013 - Astronomer John Gizis of the University of Delaware, working with data obtained by NASA's Kepler telescope, is studying a highly unusual dwarf star and its powerful flares that may hold clues to the likelihood of life on other planets as well as to the behavior of our sun. Gizis, associate professor in the Department of Physics and Astronomy, discovered the star two years ago using a ground-based telescope and now has conducted additional research using Kepler observations over the past two years.

Xiao Lab publishes Nature Communications article on the emerging field of spin-orbit torques

May 1, 2013 - The recent Nature Communications article by Prof. Xiao and his graduate students and postdocs, including also a collaborator from the State Key Laboratory of Electronic Films and Integrated Devices in China, has provides perhaps the key insight into the controversy surrounding recently emerged fields of spin torques driven by spin-orbit (SO) coupling generated by relativstic effects in solids. 

Topological insulators open new avenues for spin-transfer torque and second-generation spintronics

November 2, 2012 - In the recent  Physical Review Letters article, graduate student Farzad Mahfouzi and Prof. Nikolic, in collaboration with Prof. Naoto Nagaosa  from the University of Tokyo and RIKEN Advanced Science Institute in Japan, have predicted a new type of spin-transfer torque in vertical heterostructures involving recently discovered three-dimensional topological insulators (TIs).
