Squeezing an electron crystal

November 8, 2019

Written by Katherine Wright, senior editor for Physics, and re-published here with permission. See original post: https://physics.aps.org/synopsis-for/10.1103/PhysRevLett.123.197701 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 […]

NSF awards $1.6M Quantum Idea Incubator Award to U-led team

October 9, 2019

The National Science Foundation has awarded $1,635,591 to scientists from the University of Utah and a collaborator from University of California, Los Angeles, to research one of the biggest hurdles to quantum computing—the quantum logic units, or “qubits,” that carry information. The award is one of 19 Quantum Idea Incubator grants totaling $32 million funded […]

Limitation exposed in promising quantum computing material

July 16, 2019

Quantum computers promise to perform operations of great importance believed to be impossible for our technology today. Current computers process information via transistors carrying one of two units of information, either a 1 or a 0. Quantum computing is based on the quantum mechanical behavior of the logic unit. Each quantum unit, or “qubit,” can […]

Birds’ surprising sound source

April 10, 2019

All air-breathing vertebrates have a larynx—a structure of muscles and folds that protects the trachea and, in many animals, vibrates and modulates to produce a stunning array of sounds. But birds, although they have larynges (plural of larynx), use a different organ to sing. It’s low in the airway, down where the trachea branches to […]

New phenomenon discovered that fixes a common problem in lasers: Wavelength splitting

February 7, 2019

A team led by University of Utah physicists has discovered how to fix a major problem that occurs in lasers made from a new type of material called quantum dots. The never-before-seen phenomenon will be important for an emerging field of photonics research, including one day making micro-chips that code information using light instead of […]

U honors student awarded prestigious Churchill Scholarship

January 22, 2019

Cameron Owen of Boise, Idaho, a senior honors student majoring in chemistry and physics and minoring in mathematics, has received the prestigious Churchill Scholarship to study at the University of Cambridge in the United Kingdom. He is one of only 15 students nationally to receive the award this year and is the fourth consecutive Churchill […]

Spintronics “miracle material” put to the test

January 10, 2019

When German mineralogist Gustav Rose stood on the slopes of Russia’s Ural Mountains in 1839 and picked up a piece of a previously undiscovered mineral, he had never heard of transistors or diodes or had any concept of how conventional electronics would become an integral part of our daily lives. He couldn’t have anticipated that […]

U emeriti professors awarded two of nation’s top physics prizes

October 24, 2018

Dannie Heineman Prize for Mathematical Physics Bill Sutherland, emeritus professor of physics at the University of Utah, was awarded the 2019 Dannie Heineman Prize for Mathematical Physics, which he will share with Professor Michel Gaudin at the Institute for Advanced Study and Francesco Calogero, professor of physics at Sapienza University of Rome. The prize is […]

Mountain-top observatory sees gamma rays from exotic Milky Way object

October 3, 2018

The night sky seems serene, but telescopes tell us that the universe is filled with collisions and explosions. Distant, violent events signal their presence by spewing light and particles in all directions. When these messengers reach Earth, scientists can use them to map out the action-packed sky, helping to better understand the volatile processes happening […]

University of Utah engineers join DARPA effort to remake U.S. electronics

July 24, 2018

Pierre-Emmanuel Gaillardon, assistant professor of electrical and computer engineering at the University of Utah, was awarded close to $2 million over four years to lead two projects for the Defense Advanced Research Projects Agency (DARPA)’s new Electronics Resurgence Initiative (ERI) “Page 3” programs. Gaillardon and the rest of the awardees were announced on Monday, July […]
