“SuperTIGER may launch any day now, and X-Calibur will be flight-ready right after them,” said Henric Krawczynski, professor of physics in Arts & Sciences. While they wait for launch from Antarctica, the team is eating well, skiing and seal watching. Follow their blog to see how the missions featuring WashU technology fare.

It’s going to be a sunny, cold summer this December for scientists headed to Antarctica. McMurdo Station, the continent’s bustling metropolis of roughly 1,000 residents, will be home to researchers hoping to understand more about some of the most exotic phenomena in the universe – neutron stars and black holes.
Professor Bhupal Dev was recently interviewed and quoted in an article on LiveScience.
James Buckley, a professor in the Department of Physics, received a three-year, $962,000 grant from NASA to support the development of a novel imaging calorimeter for gamma ray and cosmic ray studies.
Over thousands of years, by trial and error, humankind has learned how to produce superior materials for different types of processing. Physicist Ken Kelton talks about materials through the ages.
Erik Henriksen, assistant professor of physics, received a $406,000 National Science Foundation grant toward a project titled "Pursuit of quantum spin liquids in exfoliated anti-ferromagnetic insulators." Henriksen was also awarded $69,000 from Zyvex Labs to collaborate on the development of atomically precise fabrication and contactless measurement technology.
A cross-disciplinary team of chemists and physicists from Washington University in St. Louis is building a better computer chip to improve detection and surveillance for the illegal transport of nuclear materials at U.S. borders.
Kater Murch, Associate Professor of Physics, and colleagues find quantum ‘Maxwell’s Demon’ may give up information to extract work
Professor Krawczynski's article on testing Einstein's predictions for rotating black holes is an Editor's Choice for the August 2018 issue of General Relativity and Gravitation

Professor Martin Israel received the Dean’s Medal this spring. He discusses his background and career in this video profile from Arts & Sciences.
Alex Meshik, research professor in physics in Arts & Sciences, received a $1.1 million award from NASA in support of a project titled “Analyses and interpretations of noble gases delivered by Genesis and Stardust missions – Phase 2.”
New particle accelerators will probe how charged particles assume a new identity, or change ‘flavor,’ theorists say
Ryan Ogliore, assistant professor of physics in Arts & Sciences, received a $147,000 grant from NASA in support of a project titled “Investigating nearby supernovae through analyses of ancient and contemporary stardust.”
On the fifth Monday of each semester, a new source of productive procrastination becomes available: Course Listings go up on WebStac.
The Dean’s Medal honors a friend whose dedication and support have been exceptional and whose leadership, advice, and inspiration have served to place Arts & Sciences at the heart of one of the world’s premier universities.
"...your research ranks among the top 1% most cited works in your field and during its year of publication, earning the mark of exceptional impact. It is truly an honor to recognize researchers like you for your dedication and focus to expanding the sphere of human knowledge..."
Graphene has generated a lot of excitement in the materials-science research community because of its potential applications in batteries, solar energy cells, touch screens and more.
He plans to work with other physics faculty to help them incorporate this approach. He also is broadening his use of flipped classrooms to include it in advanced-level classes and in the lab.
How they made their analysis and reached this predictive framework is part of their decade-long pursuit as well.
“It’s reminiscent of the magic tricks that involve a ball placed under one of two cups and the cups are shuffled around — except this time, the ball can be under both cups at the same time,
What seems like luck is probably a lack of knowledge—and an incredibly exciting opportunity. The data generated by the booming field of microbiome research contains many hints that our familiar assumptions might in fact be wrong at the scale of microbial life. Microbiology might well be at the brink of revolutionizing how we think about living matter
Researchers at Washington University are using a 6,000-pound device called SuperTIGER. It converts cosmic rays into light and allows scientists to study the elements they contain. Bob Binns, a professor of physics who has been working on the SuperTIGER project since 1993, wants to test a theory about where cosmic rays come from.
Physicist Mark Alford first encountered this experiment, called the Bell test or the Einstein-Podolsky-Rosen experiment, in the form of pages of equations and, taking pity on students everywhere, has found a way to describe it that more of us can understand. Here, he explains the logic behind a famous experiment designed to tell whether quantum mechanics is spooky or nonspooky.
One sign of the weirdness of glass is that the transition from liquid to a glass is much fuzzier than the transition from liquid to crystalline solid.
The quantum Zeno effect was named by analogy with the arrow paradox conceived by the Greek philosopher Zeno: At any given instant of time, an arrow in flight is motionless; how then can it move? Similarly, if an atom could be continually measured to see if it is still in its initial state, it would always be found to be in that state.
On the other hand, experimental psychologists who have studied the decision behavior of people in such situations as the fussy suitor problem have shown that people tend to stop searching too soon
Each year, the academy seeks nominations of outstanding women and men in science, engineering and technology who are known worldwide for their scientific contributions to research, industry and quality of life. Those recognized also have a record of excellence in communicating with the public or mentoring colleagues.
If a neutron star were any denser, it would collapse into a black hole and disappear, Alford says. “It’s the next to last stop on the line.”
How does Bender know which problem to pick, which problems might yield when pushed in this way? “You can smell it,” he said
Prof. James G. Miller was named the recipient of the 2016 Rayleigh Award at the International Ultrasonics Symposium held this year in Tours, France.
Washington University Professors Krawczynski and Kislat are leading a campaign to launch the 8-m focal length X-ray telescope X-Calibur on a stratospheric balloon flight
This manner of detection turns everything upside down, he said. All that a photon detector can tell you about spontaneous emission is whether an atom is in its excited state or its ground state. But the interferometer catches the atom diffusing through a quantum “state space” made up of all the possible combinations, or superpositions, of its two energy states.
