Former Postdoc Rusev Published in PRL

Wednesday, February 6th, 2013

KONICA MINOLTA DIGITAL CAMERADr. Gencho Rusev, former Research Scientist in Prof. Werner Tornow’s research group at TUNL and now at Los Alamos National Laboratory, is the first author of a Physical Review Letter article [PRL 110, 022503 (2013)] about the “Fine Structure of the Giant M1 Resonance in 90Zr”. This work was carried out with other scientists from TUNL and abroad using Duke’s High-Intensity Gamma-ray Source (HIgS ). You can read the PRL article online here.

T2K awarded prize by the French magazine “La Recherche”

Wednesday, November 21st, 2012

Duke postdoc Tarek Akiri from the neutrino group brings us news from the French press. On October 23rd, one of the most popular science journals in France “La Recherche” awarded the T2K experiment a prize for its paper published in June 2011: “Indication of electron neutrino appearance from an accelerator-produced off-axis muon neutrino beam”. This paper reported the first indications of appearance of electron neutrinos in a beam of muon neutrinos due to oscillations. This allowed the first measurement of an oscillation parameter crucial for the understanding of neutrino properties and their impact on the universe, and was the topic of Duke graduate student Josh Albert’s thesis.

A jury composed of ten members from different science fields gives this award each year. It rewards each year’s breakthroughs in research in 11 science fields, and T2K won the physics prize. This is quite an honor in France, and all of the members of the neutrino group who have been working hard on the experiment were excited to hear the news.

Two HEP Group Postdocs Win Awards

Tuesday, June 19th, 2012

Two postdocs from the high energy physics group were recognized for their work this week at the Fermilab Users Meeting.

Alex Himmel (from the neutrino group) was awarded the URA thesis award for his thesis “Antineutrino Oscillations in the Atmospheric Sector” which he completed at Caltech just before coming to Duke.

Bodhitha Jayatilaka, who is a postdoc working with Prof. Ashutosh Kotwal on the CDF experiment, won this year’s URA Tollestrup Award for Outstanding Postdoctoral Research for his work “Precision Measurement of the W Boson Mass at CDF”. Following a rigorous selection process from all postdocs who are conducting research at Fermilab, the Tollestrup Award Committee chose Jayatilaka for this prestigious award citing his contributions to the recent, most precise measurement of the W boson mass. Dr. Jayatilaka  was presented this award at the Fermilab Annual Users Meeting in June by Dr. Alvin Tollestrup, who motivated the construction of the Tevatron proton-antiproton collider at Fermilab and was the founding co-spokesperson of the CDF experiment.

Congratulations to both of them!

Former Researcher Raut’s HIGS Research Published

Thursday, April 26th, 2012

Dr. Rajarshi Raut, former Research Associate in  Prof. Werner Tornow’s research group, is the first author of a Physical Review Letter article [PRL 108, 042502 (2012)] about the measurement of the photodisintegration cross section of 4He. This work was carried out at TUNL’s High-Intensity Gamma-ray Source (HIgS ). Related work on 3He was published a few months earlier in Physics Letters by W. Tornow et al. [Phys. Lett. B 702 121 (2011)].

President Brodhead Visits the Behringer Lab

Friday, April 20th, 2012

On February 4, 2012, Duke University President Richard Brodhead visited the Physics Department and in particular, explored the mysteries of granular materials. He began his visit by trying a simple granular experiment on his own, with a little help from Prof. Bob Behringer.

Jie Ren, a Ph.D. student, showed President Brodhead how her experiment works. She and post-doc Joshua Dijksman are studying the basic statistical physics of shear granular material. Along the way President Brodhead asked a number of questions that showed his quick grasp of the physics!

He then learned about Duke Physics’ ‘earthquake machine’, here demonstrated by Bob Behringer. This experiment probes the same kind of stick-slip that occurs in earthquake fault zones like the San Andreas, with the advantage that the experimenter can see exactly what is happening, and of course the energy released is not so dangerous.

At President Brodhead’s  last stop, graduate student Abe Clark showed off his apparatus that is used to probe the way a meteor behaves when it strikes the earth. In this picture, from left to right: President Brodhead, holding a polarizer, Prof. Haiyan Gao, Chair Department of Physics, Hu Zheng, visiting scholar, and Ph.D. students Jie Ren, Somayeh Farhadi and Abe Clark.

Friday, February 3rd, 2012

Graduate student Seth Cohen

Prof. Daniel Gauthier, postdoc Hugo Calvalcante and graduate student Seth Cohen‘s paper “Subwavelength Position Sensing Using Nonlinear Feedback and Wave Chaos” was recently published in Physics Review Letters. The article was selected as an editor’s suggestion and Cohen was interviewed by Duke Today. The story is featured on the Duke Research Blog.

News from Prof. Behringer’s former group members

Friday, September 16th, 2011

In the past six months, four former students or post-docs of Prof. Robert Behringer have received tenure or other honors. They are as follows:

  • Karen Daniels, NC State
  • Corey O’Hern, Yale
  • Jeff Olafsen and his wife Linda Blue, Baylor
  • Matthias Sperl now has a permanent position as group leader in charge of a granular group at the DLR in Germany (their equivalent of NASA)

Also, some slightly older news, Behringer’s former post-doc Brian Utter received tenure from James Madison about a year ago, former post-doc Lou Kondic is now full prof in math at NJIT, and former student Mark Shattuck is tenured at City College. Former post-doc Jie Zhang just received three outstanding offers from universities in China, and he will return in January.

Duke Physics hosts Physics for Females

Thursday, September 8th, 2011

On June 6 students, postdocs and faculty members worked together to coordinate an outreach event for female high school students called “Physics for Females.” Several Duke students, postdocs, staff, and professors volunteered to help with the event. The students were able to go on lab tours, hear a talk about special relativity and particle physics by Prof. Kate Scholberg, and play with physics toys and demos. The group hopes to hold a similar event next year.

The event team included the following Duke Physics people:

Kristine Callan
Albert Chang
Abe Clark
Seth Cohen
Joshua Dijksman
Someyah Farhadi
Prof. Henry Greenside
Hannah Guilbert
Fritz Kretzschmar
Jeff LaCosse (Durham School of the Arts)
George Laskaris
