IceCube Neutrino Observatory at the South Pole

The UD Astroparticle Physics team led by Prof. Gaisser is part of an international collaboration working at the world's largest neutrino detector, encompassing a cubic kilometer of ice. IceCube searches for neutrinos from the most violent astrophysical sources: events like exploding stars, gamma ray bursts, and cataclysmic phenomena involving black holes and neutron stars.Read More
Spin pumping in magnetic tunneling nanostructures

Joint experimental and theoretical efforts of researchers from the UD Center for Spintronics and Biodetection have demonstrated for the first time that pure spin currents can be generated in microwave driven magnetic tunnel junctions without any applied voltage. Pure spin currents are not accompanied by any net charge current and offer a pathway toward ultra-low-dissipation nanodevices.Read More
Secrets of water revealed from first principles quantum simulations

Prof. Szalewicz's group has developed new first-principle high performance simulations of water molecules. They will aid science and industry in a broad range of applications, from biological investigations of protein folding and other life processes, to the design of the next generation of power plants.Read More
VERITAS scans gamma-rays from extreme astrophysical phenomena in the universe

The Bartol Research Institute is a part of the VERITAS collaboration which operates the highest sensitive instrument to detect very-high energy gamma-rays from extreme astrophysical phenomena in the Universe. VERITAS is now scanning the night sky searching for remnants of exploded stars, distant active galaxies, powerful gamma ray bursts, and evidence of mysterious Dark Matter particles. Read More

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.
