Shimon Kolkowitz, a University of Wisconsin–Madison assistant professor of physics, has been selected as one of 22 members of the 2019 class of Packard Fellows for Science and Engineering.
The fellowship, awarded to early-career scientists from across the U.S., provides $875,000 of funding over five years. Kolkowitz will use the funds to develop his research program in ultra-precise atomic clocks, which he will use to investigate such fundamental aspects of physics as the relationship between quantum mechanics and gravity and the nature of dark matter.
The Physics Board of Visitors, their families and friends visited CERN, Geneva, to learn about the department research activities there. Professors Sau Lan Wu, Cary Forest and Sridhara Dasu hosted them. Thanks to Sylvie Padlewski and Aimee Lefkow for help organizing the event.
All prospective undergraduate Physics majors are invited to attend our Physics Major Fair on Thursday, Oct 17 from 4:30-5:30pm in the Physics Museum. Connect with facutly + current undergrad majors, learn about our clubs and student orgs, and eat tasty treats.
As the field of quantum computing grows, American Family Insurance and the University of Wisconsin–Madison’s Wisconsin Quantum Institute (WQI) keep pace, announcing plans to work together in partnership to expand quantum computing research at UW.
American Family’s new relationship with WQI is part of the company’s ongoing partnership with UW–Madison supporting students, academic programs, research, athletics and charitable activities. This endeavor will help to attract top graduate students to UW–Madison and will fund a campus seminar series that brings leaders in the field to Madison. In turn, WQI researchers will collaborate with American Family researchers.
On September 20, Prof. Francis Halzen was presented with the 2018 Bruno Pontecorvo Prize. This international award is presented annually by the Joint Institute for Nuclear Research Scientific Council for achievements in elementary particle physics. Congrats!
In new research published Sept. 26 in the journal Nature Communications, Physics professor Pupa Gilbert and her collaborators, including MIT engineering Professor Markus Buehler and University of Pittsburgh oral biology Professor Elia Beniash, used advanced imaging techniques to see a clearer picture of the organization of individual enamel crystals in human teeth. They found that these crystals are not perfectly aligned, as had been previously thought, and that this misorientation likely deflects cracks, leading to enamel’s lifelong strength.
The US Department of Energy recently announced the funding of another set of quantum science-driven research proposals, including that of Sau Lan Wu, Enrico Fermi professor of physics and Vilas Professor at the University of Wisconsin–Madison. With the funding, Wu and her collaborators seek to tap into the power of quantum computing to analyze the wealth of data generated by high energy physics experiments.
The title of Wu’s DOE approved project is: “Application of Quantum Machine Learning to High Energy Physics Analysis at LHC using IBM Quantum Computer Simulators and IBM Quantum Computer Hardware”.
Professors Tulika Bose and Maxim Vavilov have been elected 2019 American Physical Society Fellows. The APS Fellowship Program recognizes members who have made exceptional contributions to the physics enterprise in physics research, important applications of physics, leadership in or service to physics, or significant contributions to physics education. Each year, no more than one half of one percent of the Society membership is recognized by their peers for election to the status of Fellow in the American Physical Society. This year, 168 Fellows were selected and recognized for their contributions to science. Congrats, Tulika and Maxim!
Congrats to second-year grad students Megan Tabbutt and Aedan Gardill, both in the Kolkowitz Group, on earning National Defense Science and Engineering graduate fellowships! The awards provide up to three years of funding for these students to pursue their research projects, which they describe below:
Megan Tabbutt
Optical atomic clocks are now the most precise time keepers in the world, keeping time to better than one second over the age of the universe. With support from the NDSEG, I will work with my collaborators to build a new “multiplexed” strontium optical lattice atomic clock, which will consist of two clocks in one vacuum vessel. We will use this new kind of clock to perform tests of Einstein’s theory of relativity, such as measuring the relativistic effects of gravity on the passage of time at the millimeter scale, which may one day have applications ranging from the prediction of volcanic eruptions to water resource management and flood prevention. We will also engineer strong interactions between the atoms that make up the clock to generate entangled states for quantum enhanced clock performance, among other pursuits.

Superconducting qubits are a promising system for quantum computing, but external sources of "noise" currently limit their usefulness. A better understanding of the sources of this noise in the qubits should help advance quantum computing efforts. With the NDSEG fellowship, my research will focus on using nitrogen vacancy centers in diamond as sensors with nanometer-scale resolution. We will develop and apply novel sensing techniques to study interesting solid state systems, such as investigating the origins of noise that currently limit superconducting qubit performance.
