Prof. Matthaeus helps explain characteristics of swirling solar wind

November 10, 2015 - Just a few hundred yards from the house where Italian astronomer Galileo Galilei (1564-1642) lived in Arcetri for the last nine years of his life, the University of Delaware's William Matthaeus is working to further the world's understanding of the heliosphere - the big bubble of magnetism that holds the solar system together - and especially its turbulent nature. Matthaeus, professor of physics and astronomy who specializes in heliospheric plasma physics and turbulence theory, is steering the Arcetri 2015 Workshop on Plasma Astrophysics this week.

Physics at the edge of the cut

October 14, 2015 - Perturbation theory (PT) is an essential tool for the mathematical modeling of physical systems. It allows one to approximate the solution of a complex problem in terms of the solution of a much simpler unperturbed one. PT can be used to find approximations to almost anything and it is used across fields in the physical and engineering sciences: the deflection of a wing and the magnetic moment of nuclei furnish examples from an endless list of possible applications.

Nano Letters article features new effect in the nascent field of topological spintronics

September 18, 2015 - In the recent Nano Letters article, an interdisciplinary team of physicists, materials scientists and electrical engineers, including Prof. Nikolic and DPA alumni Dr. Farzad Mahfouzi, have demonstrated novel effect in topological-insulator/ferromagnet (TI/FM) heterostructures exposed to microwave radiation.

Cholesterol: More than just heart attacks

September 2, 2015 - In a recent Biophysical Journal article featured on the cover, Prof. Edward Lyman shows a configuration sampled by a molecular dynamics simulation of a mixture of two lipids and cholesterol, modeled in all-atom detail. Read more on the Website of Biophysical Journal.

UD researcher helps to refine precision of atomic clock

May 4, 2015 - For those whose kitchen clocks almost never agree with their nightstand clocks, for those who grouse about forcing their watches to spring forward or fall back, the work University of Delaware physicist Marianna Safronova and other researchers are doing may be nothing short of mystifying.
