- Physicists skirt thermal vibration, transfer optical signal via mechanical oscillator
November 15, 2012
Using tiny radiation pressure forces — generated each time light is reflected off a surface — University of Oregon physicists converted an optical field, or signal, from one color to another. Aided by a "dark mode," the conversion occurs through the coupling between light and a mechanical oscillator, without interruption by thermal mechanical vibrations.

November 2, 2012
At Seattle's Living Computer Museum which opened in October, one of the oldest exhibits at the is a PDP-7 made by Digital Equipment Corporation. Designed in the
mid-1960s, it is believed to be the only working model of this machine in the world. The computer operated in Harlan Lefevre's lab for many years.

- Nearly a thousand showed up for the first North American
Physics Slam at UO
March 31, 2011
Eight hundred turned out at UO on March 22, 2011 for the first physics slam in North America.
The slam was hosted in concert with the American Linear Collider Physics Group
ALCPG11) held at UO. The overflow crowd filled Columbia 150 and Pacific 123
to hear five physicists from around the world compete with their explanations of dark matter,
extra dimensions, neutrinos and astrophysics, particle detectors, and
superconducting cavities for particle acceleration. The event was recorded by various news media:
- BBC Television Show Analyzes Pollock's Fractals
March 2, 2011
The BBC is filming a three-part series called "The Code" hosted by Marcus du Sautoy, a professor of mathematics at Oxford. The program is about the structural systems that determine the form of everything from beehives and bubbles to music, computer animation and the weather. Richard Taylor was featured to explain how the mathematical "code" behind one of Pollock's drip paintings was unique enough to expose counterfeits. In the picture, Richard Taylor and Marcus du Sautoy discuss the physics behind the fractal "code" found in nature and in Pollock's poured paintings, while Rick Montgomery operates the Pollockizer, a driven pendulum whose paint-filled bob splatters paint in patterns reminiscent of Jackson Pollock.
- Sparking girls to be scientists
Feb. 13, 2011
Oregon Center for Optics
The Science Program to Inspire Creativity and Excellence is an informal science outreach program targeting middle school aged girls. The goal of the program is to inspire young women to pursue careers in the science, technology, engineering, and mathematics disciplines by providing them with fun, hands-on science activities and camps.
- Graham Kribs, adventurous Ben Lee fellow
Feb. 4, 2011
Fermilab Today profiled Graham Kribs, preceding a seminar talk he gave to the joint experiment/theory seminar as a Ben Lee Fellow.
- Physics and leaf-cutter ants
Jan. 5, 2011
Leaf-cutter ants rely on their razor-sharp mandibles to cut leaves to pieces. But over time, their mandibles dull. Physicist Robert Schofield, of the University of Oregon, looked at what happens when the aging ants struggle with their snipping. He and his colleagues found they take on a new job.
- Physicists Break Color Barrier for Sending, Receiving Photons
Oct. 2, 2010
University of Oregon scientists have invented a method to change the color of single photons in a fiber optic cable. The laser-tweaked feat could be a quantum step forward for transferring and receiving high volumes of secured data for future generations of the Internet.
Research may shed light on solar cells
Sept 13, 2010
In collaboration with colleagues at Oregon State University and the University of Illinois, we have initiated a project to improve the efficiency of solar cells, by improving their quantum efficiency using an approach called heterojunction-assisted impact ionization. This approach is based loosely on advanced semiconductor detectors in which energetic carriers produced by higher energy photons decay by production of additional electron-hole pairs by impact ionization. Our approach could be applied to existing PV material systems, and we are also seeking new low-cost, environmentally benign materials for future applications.
Eternal black holes are the ultimate cosmic safes
Sept 3, 2010
While investigating whether white holes (time reversed black holes)
emit Hawking radiation, Hsu discovered that certain quantum black hole
states are eternal and do not evaporate.
Camp for a cause
Aug 5, 2010
A week-long Physics and Human Physiology camp for high school students, part of an umbrella of programs spanning several departments at UO that especially targets students from low-income backgrounds, ran successfully in August. We explored both physics and physiology with hands-on activities and visits to several labs, getting our hands wet with soap films, examining human cadavers, climbing rock walls, and more. (Organizers: Raghuveer Parthasarathy, Physics; Paul van Donkelaar, Human Physiology.)
Putting performance art into physics

The most exciting time in physics in my entire professional career
Mar 31, 2010
The world's largest atom smasher crashed together two minuscule particles racing at unheard of speeds in conditions simulating those just after the Big Bang - a success that kick-started a megabillion-dollar experiment that could one day explain how the universe began.
The mysterious Universe - brought to Albuquerque
November 5, 2009
Even though University of Oregon professor and Americas regional contact for the ILC physics and detectors studies Jim Brau had specifically invited a young audience to his public lecture on 1 October in the University of Albuquerque, he thought of teenagers and university students rather than seven-year-olds. But Brau gave particle physics one of its youngest fans - little Abigail Zwartz was so gripped by his talk that she took notes eagerly and even presented them in school the next day.
- Uncertainty Principle Used To Detect Entanglement Of Photon Shared Among Four Locations
Steven van Enk
Pavel Luogovski and Steven van Enk, in collaboration with scientists at the California Institute of Technology have developed an efficient method to detect entanglement shared among multiple parts of an optical system. They show how entanglement, in the form of beams of light simultaneously propagating along four distinct paths, can be detected with a surprisingly small number of measurements.
What happens if atom smasher recreates Big Bang?
The border of Switzerland and France still exists. That's where scientists got the Large Hadron Collider up and running early on Wednesday. University of Oregon physicist Graham Kribs has been working on the project that hopes to find the answer to where matter comes from.
Atomic One-Way Barriers and Quantum Measurements
We realized an asymmetric optical potential barrier for ultracold rubidium atoms using laser light. In this one-way barrier, atoms impinging from one side are transmitted, but they are reflected from the other. This turns out to be a realization of Maxwell's demon and has potential implications for cooling atoms and molecules not amenable to standard laser-cooling techniques.
