Charge, spin and valley Hall effects in disordered graphene reviewed

December 23, 2016 - In the recent review article, Prof. Nikolic and collaborators from Grenoble and Barcelona provide comprehensive coverage of different types of Hall effects, both in their classical and quantized versions, observed in graphene where electrons can scatter elastically from adatoms, vacancies and impurities or inelastically from lattice vibrations. 

Spin hall effect and origins of nonlocal resistance in adatom-decorated graphene

October 21, 2016 - In the recent Physical Review Letters article, Prof. Nikolic, visiting graduate student and Fullbright Scholar Juan Manuel Marmolejo-Tejada from Colombia and collaborators from France and Spain have performed detailed theoretical and computational analysis in order to resolve fierce controversy surrounding very recent experiments reporting an unexpectedly large spin Hall effect (SHE) in graphene decorated with adatoms.

Daicar-Bata Prizes awarded to UD doctoral students Nieto-Pescador, Wise

September 29, 2016 - Jesus Nieto-Pescador and Alexander Wise, doctoral students at the University of Delaware, Department of Physics and Astronomy, have been awarded prestigious Daicar-Bata Prizes. Each year, the department recognizes exceptional doctoral student accomplishments by awarding two Daicar-Bata Prizes – one for the best research paper in a physics or astronomy peer-reviewed journal published during the previous academic year and another for the highest grade point average in physics and astronomy courses at the end of the student's sixth semester in the program.

UD's Matthaeus takes reins of Delaware Space Grant in 25th anniversary year

September 8, 2016 - Many are the mysteries that University of Delaware astrophysicist William Matthaeus has explored in our galaxy for the past four decades or so. But the news from NASA this week is not so hard to figure. Planet Earth's foremost space agency has named Matthaeus to direct the Delaware Space Grant (DESG), which marks its 25th anniversary this year. Matthaeus succeeds Dermott Mullan, UD professor of astronomy and physics, who was director from 2005-15.

Prof. Dodson-Robinson comments on NASA mission to Jupiter

July 1, 2016 - As NASA’s Juno spacecraft arrives at Jupiter on July 4, UDaily checks in with Sally Dodson-Robinson, an expert on planet formation in the University of Delaware's Department of Physics and Astronomy, for a deeper look at the mysterious world it will explore.

Prof. Gizis discovers an "ultracool" brown dwarf that can generate flares stronger than the sun's

June 13, 2016 - Although astronomers often refer to brown dwarfs as “failed stars,” scientists at the University of Delaware have discovered that at least one of these dim celestial objects can emit powerful flashes of light. A research team led by Prof. Gizis, has discovered an “ultracool” brown dwarf known as 2MASS 0335+23, with a temperature of only 4400°F that can generate flares stronger than the sun’s. Gizis reported on the finding on June 13 at the annual meeting of the American Astronomical Society in San Diego.
