Evidence for a common physical origin of the Landau and BEC theories of superfluidity

November 20, 2014 - In a recent Physical Review Letter article, which is highlighted by PRL as an “Editors Suggestion” to read, Prof. Mulders, Prof. Glyde and collaborators combine neutron scattering and torsional oscillator measurements to show that two originally quite separate theories of superfluidity in liquid 4He are based on mutually consistent liquid properties (phonons and BEC) that have a common physical origin.

Highly charged ions for atomic clocks and quantum information

July 22, 2014 - In the recent Physical Review Letters article, Prof. Safronova and her collaborators from the US, Australia and Russia have proposed 10 highly charged ions as candidates for the development of next generation atomic clocks, search for variation of fundamental physical constants, and quantum information processing. They predicted the ion properties crucial for the experimental exploration and highlighted particularly attractive systems for these applications.

Harnessing fundamental physics of topological insulators for thermoelectric energy conversion

June 19, 2014 - In the recent Nano Letters article, Prof. Nikolic and DPA graduate student Po-Hao Chang, in collaboration with Prof. Naoto Nagaosa and Prof. Mohammad Saeed Bahramy from the University of Tokyo and RIKEN Center for Emergent Matter Science in Japan, have proposed a new type of nanoscale thermoelectric which exploits fundamental physics of topological states of matter to convert waste heat into electricity.

Spin-Seebeck effect on the surface of topological insulators

May 14, 2014 - In the recent Physical Review B article, Prof. Nikolic and physics graduate students Po-Hao Chang and Farzad Mahfouzi, together with Prof.

UD scientists involved in 2013 Breakthrough of the Year in physics

December 13, 2013 - The IceCube South Pole Neutrino Observatory, an international scientific collaboration that includes researchers from the University of Delaware, has been awarded the 2013 Breakthrough of the Year by the British magazine Physics World. The Antarctic observatory has been selected for making the first observations of cosmic neutrinos. These particles, the “high-energy messengers of the universe,” zip through space and may yield important clues to the origins of the universe.
