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).  

DPA ranked among the top 200 physics departments in the world according to research impact and excellence

October 16, 2012 - The University of Delaware is listed among the top universities in the world, based on a new report on the production and impact of scientific papers. The 2012 Performance Ranking of Scientific Papers for World Universities, released Oct. 9 by National Taiwan University, is based on statistics of scientific papers that reflect three major performance criteria: research productivity, research impact and research excellence.

Widely used Platinum-based detection of pure spin currents under scrutiny

October 7, 2012 - In the recent Physical Review Letters article, Prof. Xiao's group with collaborators from the Johns Hopkins University and the Arizona State University have performed detailed magnetotransport measurements, both electrical and thermal, to conclusively show strong ferromagnetic characteristics in thin Platinum (Pt) films on the ferromagnetic insulator YIG due to the magnetic proximity effects.
