The human immunodeficiency virus, or HIV, wages war in our bodies using a strategy evolved over millions of years that turns our own cellular machines against themselves. Despite massive strides in understanding the disease, there are still important gaps. For years, scientists at the University of Utah wished there was a way to visualize how the virus and its molecules interact with human cells in real time. So, a research group developed one.
The next generation of information technology could take advantage of spintronics—electronics that use the minuscule magnetic fields emanating from spinning electrons as well as the electric charges of the electrons themselves—for faster, smaller electronic devices that use less energy. Newly published work by scientists at the National Renewable Energy Laboratory and the University of Utah may figure into the future success of spin-based electronics.
Twelve students from the Physics & Astronomy Department attended the 2019 Sigma Pi Sigma Physics Congress (Phys Con) in Providence, Rhode Island, the largest gathering of undergraduate physics students in the world. The biannual conference is sponsored by the American Institute of Physics.
the Spectrum is published twice a year by the Department of Physics & Astronomy and provides interesting information about the department.
The Wigner crystal is an elusive beast. Predicted in 1934, this crystal of electrons, which is one of the most strongly correlated states of matter, forms when the electron density is ultralow. But a lack of clean enough systems with that property make it hard to measure. Within the last few months, researchers have imaged its structure. Now another group, led by Vikram Deshpande at the University of Utah, Salt Lake City, has measured the energy required to add an electron to the crystal, a quantity that reveals the interaction strength of the system.
