Unraveling quantum states of charge and spin in topological spintronics

August 11, 2017 - In the recent Nano Letters article, Prof. Nikolic, postdoctral fellow Dr. Kapildeb Dolui, visiting graduate student Juan Manuel Marmolejo-Tejada from Colombia and DPA alumni Dr. Po-Hao Chang, together with collaborators from Denmark and Croatia, have developed new computational approach offering a unique microscopic insight into quantum states of charge and spin at  topological-insulator/ferromagnetic-metal (TI/FM) interfaces.

Dr. Prachanda Subedi 2017 Winner of the Donald L. Turcotte Award
Dr. Prachanda Subedi graduated with his PhD from the University of Delaware Department of Physics and Astronomy this spring.

UD Day in D.C. shows off astrophysics virtual reality

March 16, 2017 - From the heliosphere to the inner workings of the human brain, the richness of human culture, the way we get and consume energy and the all-fronts assault on disease, disorders, the effects of traumatic injury and human suffering, research at the University of Delaware touches life at just about every global address. For a few hours Wednesday, a sample of that broad expanse of work was on display in the Hart Senate Office Building.

Star with seven possible Earth-like planets has UD connection

February 22, 2017 - When NASA announced in a news conference Wednesday, Feb. 22, that researchers had found seven potentially Earth-like planets orbiting a star 235 trillion miles away, John Gizis, a professor at the University of Delaware, got a big grin on his face. Gizis actually discovered that star in 1999. “It’s extremely exciting,” Gizis said from his office in UD’s Department of Physics and Astronomy. “It’s a very small and cool dwarf star.

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.
