Dr. Xian Lu Awarded Grant from NSF’s Grand Challenges in Integrative Geospace Sciences

Dr. Lu’s proposal to the NSF Grand Challenges in Integrative Geospace Sciences program, Advancing National Space Weather Expertise and Research award Societal Resilience (ANSWERS), has been awarded. This grant will support a multidisciplinary team led by Dr. Lu to study space weather – in particular they will explore how terrestrial weather events originating at lower altitudes and the solar wind lead to variations in space weather. The principle driver behind this work is developing the tools to better predict space weather and ameliorate the damage that can result. This award from NSF provides $900k over three years to advance this work as well as support the development of a new space weather curriculum. Please join me in congratulating Dr. Lu and her team for their success. I’m sure we all eagerly anticipate learning about the results of this work in the near future.

Prof. Yao Wang Receives Dept. of Energy Early Career Award

Professor Yao Wang was awarded a DOE Early Career Award for a proposal titled, “Analog Quantum Simulation for Solid-State Spectroscopies”. He has proposed to develop analog quantum simulation protocols for spectroscopy of quantum materials and extend this work to the simulation of spectroscopy of laser-engineered non-equilibrium matter. Quantum materials are characterized by having entangled electrons that behave in ways that cannot be described classically. Engineering such materials opens the door to developing novel types of superconductors and batteries, but to take full advantage of these possibilities, it is crucial to accurately and efficiently characterize the properties of the electrons. Classical computers are not capable of running such simulations, but quantum computers will be able to do so. The protocols developed by this work will enable theorists to harness the power of quantum machines that will be available in the near term. Dr. Wang’s work will transform our knowledge of exotic materials and has the potential to lead to breakthrough discoveries in superconductors, energy storage, and quantum devices.

The DOE Early Career Award are “a part of the DOE’s long-standing efforts to develop the next generation of STEM leaders who will solidify America’s role as the driver of science and innovation around the world.” This year 83 awards were granted to faculty at 47 different universities and 13 national labs. These awards provide $750k over five years that in the words of U.S. Secretary of Energy Jennifer M. Granholm,  “…[allows] the recipients the freedom to find the answers to some of the most complex questions as they establish themselves as experts in their fields.”

Please join me in congratulating Dr. Wang for this great honor. I’m sure we all look forward to seeing the results of this work.

 

Yang Yang Awarded Harvard-SAO Predoctoral Fellowship

Please join me in congratulating Yang Yang for being awarded a Harvard-SAO Predoctoral Fellowship. Over the past few years, several PhD students from our department have had the opportunity to work at other research institutions as part of their graduate education. Yang Yang is the fourth student in recent years (joining Amy Gall, Xiuriu Zhao, and Jordan Eagle) to be awarded this prestigious fellowship. Kudos to Prof. Takacs for the mentorship and support he has provided to help Ms. Yang achieve this opportunity. At the SAO she will use their electron beam ion trap to generate laboratory astrophysics atomic data for AtomDB, the databased maintained by SAO for the analysis of astrophysical spectra. She works closely with one of our alums, Dr. Gall, and is involved in collaborative work with the University of Georgia and Auburn University funded by NASA. This is a very exciting achievement for Ms. Yang!

An X-ray of a Kilonova

August 17, 2017 was a watershed moment for multimessenger astronomy when the gravitational waves and photons from a kilonova were detected for the first time. And GW170817 continues to surprise. A kilonova results from the merger of neutron stars and is thought to be the source of heavy elements such as gold.

Our colleague, Prof. Jon Zrake, was part of team that has monitored the evolution of X-rays from this source. Initially the source was fading, but in 2020 the fading stopped and has remained relatively constant since. This provides intriguing insight to the physics of neutron star mergers and the subsequent explosion. The behavior of the X-rays is somewhat puzzling, and this team has proffered two explanations to account for the behavior – one possibility is that we are seeing the afterglow of the kilonova. Another possibility is that we seeing the accretion signature of material falling into a blackhole formed by the merger of these neutron stars. If the constant brightness is due to an afterglow, we should see the source brighten again. If the result is due to accretion into the black hole, then the source should remain constant or fade away over the next few years. Either result will provide valuable insight to the physics of kilonova. This work was published in the Astrophysical Journal Letters and can be accessed here.

In Memoriam: Jian He, professor of physics

I am sorry to announce that our friend and colleague professor Jian He has passed away. Jian was a prolific scholar, caring teacher, conscientious academic Professor Jian He and his research group.citizen and most importantly a good friend.

Jian earned his Ph.D. from the University of Tennessee and came to Clemson as a postdoc in 2004. In 2008, he joined the faculty of the Department of Physics and Astronomy as an assistant professor and climbed the ranks to full professor in 2021. Jian was a prolific scholar who published more than 257 peer-reviewed papers on a variety of topics in condensed matter physics. The esteem in which he was held by his colleagues is reflected by the large number of invited talks he has presented at conferences around the world. His collaborators spanned North America, Europe and Asia. He was also selected as a member of the board of reviewing editors for the journal Science. He mentored countless numbers of students in his lab and had a particular passion for undergraduate research. Condolences have been pouring in from students and colleagues around the world.

In addition to his excellence as a scholar, he was a caring mentor to his graduate and undergraduate students. His students have been recognized with numerous awards and honors from the Barry M. Goldwater Scholarship, the Astronaut Scholarship Foundation and the NSF Graduate Research Fellowship Program. Jian went above and beyond in providing the signature Clemson Experience for students.

We physicists have a reputation for having a bit of an ego, and Jian certainly earned the right to one. But perhaps no other scientist I’ve ever known has done more to shatter that stereotype. Jian was kind, helpful and unfailingly gracious. A few years ago, I hurt my ankle and Jian happened upon me while I was limping to my car. He told me to wait where I was, and he would be right back. He ran back to Kinard and a few minutes later came back with a pair of crutches. He told me he kept a set in his office for times when he sprains his ankle playing soccer (his other passion). This is just one of many stories we could tell that exemplify his kindness.

Jian will be missed but not forgotten. His example will serve as motivation to pursue excellence in our scholarly and teaching efforts as well as in showing kindness to those around us. To honor this passion for student engagement, we have established the Jian He Memorial Fund to provide support to undergraduate research in our department. Gifts can be sent to the Clemson University Foundation, P.O. Box 1889, Clemson SC 29633-1889 or call 864-656-5896. Online gifts can be made here.
