Coherent Magnetic Response at Optical Frequencies Using Atomic Transitions
Monday, January 23, 2017
A paper published in Physical Review X by Nicholas R. Brewer, Zachary N. Buckholtz, Zachary J. Simmons, Eli A. Mueller, and Deniz D. Yavuz advances our understanding of the interaction of atoms and light. In optics, the interaction of atoms with the magnetic field of light is almost always ignored since its strength is many orders of magnitude weaker compared to the interaction with the electric field. The authors report the first direct measurement of a magnetic-dipole matrix element in the optical region of the spectrum. This result opens up the prospect of constructing left-handed materials using sharp transitions of atoms.
Jim Lawler Awarded 2017 LAD Laboratory Astrophysics Prize
Tuesday, January 17, 2017
The Laboratory Astrophysics Division (LAD) of the American Astronomical Society (AAS) is pleased to announce that its 2017 Laboratory Astrophysics Prize, given to an individual who has made significant contributions to laboratory astrophysics over an extended period of time, goes to James E. (Jim) Lawler (University of Wisconsin, Madison) for his contributions in atomic physics to advance our understanding of galactic nucleosynthesis and chemical evolution. His spectroscopic work has opened a new era of stellar chemistry by advancing our ability to compare nucleosynthesis predictions with accurate relative elemental abundances.
The UW–Madison Department of Physics hosted a meeting of the Conference for Undergraduate Women in Physics (CUWiP) this past weekend (Jan 13-15, 2017) at Chamberlin Hall, UW–Madison. This event was one of ten 2017 CUWiP conferences held simultaneously around the US and in Canada.
Over 140 undergraduate students from the Midwest (Wisconsin, Minnesota, Illinois, and Iowa), including students from many of the UW branch campuses, participated. The meeting included presentations from prominent women in physics, opportunities for networking, career advice and support, and a student poster session.
The CUWiP meetings are cosponsored nationally by the American Physical Society, the National Science Foundation, and the Department of Energy. The UW–Madison conference involved other collaborators and supporters, including the Department of Physics, WIPAC, the Graduate School, the College of Letters and Science, the Office of the Provost, and the Brittingham Family Foundation.
The lead organizers were Susan Coppersmith, Robert E. Fassnacht and Vilas Research Professor of Physics; Lisa Everett, Professor of Physics; Laura Fleming, Associate Instrumentation Specialist, Department of Physics; and Pupa Gilbert, Professor of Physics, Chemistry, and Geoscience. The local organizing team also included Dr. Silvia Bravo Gallart, Education and Outreach Specialist at WIPAC; Ms. Megan Madsen, Education and Outreach Coordinator at WIPAC; and Dr. Susan Nossal, Associate Scientist, Department of Physics and Director of the Physics Learning Center, as well as UW-Madison students and staff, including many graduate students in Physics, Medical Physics, Biophysics, Engineering, and Astronomy.
It was a fantastic event that inspired all in attendance.
Pupa Gilbert: Ocean temperatures faithfully recorded in mother-of-pearl
Friday, December 16, 2016
Writing online Thursday, Dec. 15, in the journal Earth and Planetary Science Letters, a team led by University of Wisconsin–Madison physics Professor Pupa Gilbert describes studies of the physical attributes of nacre in modern and fossil shells showing that the biomineral provides an accurate record of temperature as the material is formed, layer upon layer, in a mollusk.
The Physics Department lecture demonstration office (one of the largest in the nation) is looking for a fun, energetic, and loyal student with that “creative edge”: someone with a background in the physical sciences or within physics itself, someone interested to learn more about physics, physics demonstrations, and audio/video equipment. Initially for 10 hours per week, with the possibility for more hours. Freshmen are welcome and encouraged to apply. Work-study are welcome to apply. Work trial period of one semester, with the possibility of continuation throughout the summer and into following year(s).
Some general physics knowledge is a plus.
Have a desire to learn more about physics and audio-visual equipment
Must have a working knowledge of hand tools and/or willing to learn
Be able to listen and follow instructions, but also present alternative solutions to problems.
Be able to work both independently and as a team.
Able to work during most of the summer months.
Able to work on Fridays from 3pm-4:30pm
Working knowledge of Arduino, Raspberry Pi, and other microcontrollers would be awesome.
Able to lift and move equipment (35-50lbs)
Job Duties include, but are not limited to, the following:
Assist in the digitally record our weekly departmental colloquia on Friday afternoons and other lectures, and digital editing.
Assist with the physics museum and our annual physics demo shows.
Assist with researching and archiving of lecture demonstration equipment, including making and repairing equipment, fixing cabinets, data entry, labeling, and much more.
Assist with audio/video maintenance, including pulling wire, testing cables, making cable, installing equipment, labeling, and troubleshooting.
Assist with various odd jobs, cleaning whiteboards, hanging things, fixing broken items, woodworking such as sanding, painting and varnishing.
Please submit to Steve Narf (Room 2237 Chamberlin) or Jim Reardon (Room 2320g Chamberlin):
Mark Eriksson grant lead on project to get UW getting electron beam lithography system for nanotech research
Thursday, October 13, 2016
Research projects statewide, from electronics to optics and medicine, are set to benefit from a new system coming to UW–Madison that will use electron beam lithography (EBL), a specialized technique for creating extremely fine patterns — in some cases more than 5,000 times narrower than the diameter of a human hair.
Email list for undergraduates interested in physics
Monday, October 3, 2016
The Physics Department occasionally sends announcements to undergraduate physics majors about opportunities for those with an interest in physics. Now, those who have not declared a physics major can subscribe to receive such announcements. Those who have declared a major will continue to receive announcements and do not need to self-subscribe.
Construction of world’s most sensitive dark matter detector moves forward - Kim Palladino, Shaun Alsum
Tuesday, September 27, 2016
Assistant Professor Kim Palladino joined the department last year to bolster Wisconsin LZ experiment involvement last year. Prof. Palladino secured the support of the US DOE promptly last year, while she was on research leave at SLAC to lead the construction and commissioning of the LZ test system at SLAC laboratory, with graduate student Shaun Alsum. PSL engineer Jeff Cherwinka serves as the chief engineer of the LZ experiment. Professors Carlsmith and Dasu also participate in this unprecedented search for direct interactions of weakly interacting massive particles with Xenon atoms that make up the LZ.
Dan McCammon receives the 2016 NASA Exceptional Public Service Achievement Medal

Prof. Dan McCammon is being awarded a 2016 NASA Exceptional Public Service Achievement Medal in recognition for pioneering work in the study of the celestial diffuse x-ray background and the development of low temperature x-ray spectrometers that have enabled numerous NASA projects.
This award was presented to Dan at the Agency Honor Awards Ceremony, September 14, at the NASA/Goddard Space Flight Center.
Zweibel wins 2016 Maxwell Prize for Plasma Physics
Tuesday, July 26, 2016
Ellen Gould Zweibel has won the American Physical Society’s 2016 James Clerk Maxwell Prize for Plasma Physics.
The prize citation recognizes Zweibel for “seminal research on the energetics, stability and dynamics of astrophysical plasmas, including those related to stars and galaxies, and for leadership in linking plasma and other astrophysical phenomena.”
