Prof. Argüelles-Delgado Receives a 2021 IUPAP Young Scientist Prize in Astroparticle Physics.

IceCube collaborator and Harvard physics professor Carlos A. Argüelles-Delgado is the recipient of a 2021 IUPAP Young Scientist Prize in Astroparticle Physics.

Young Scientist Prizes recognize the contributions of early career physicists within the subfields of each commission of the International Union of Pure and Applied Physics (IUPAP). The accolade consists of a certificate, medal, and a monetary award, which are usually presented biannually at the International Cosmic Ray Conference; however, since the 2021 ICRC is taking place online, Argüelles accepted his award at a virtual ceremony on July 12.

In his research, Argüelles develops new techniques to study and characterize astrophysical neutrinos to search for new neutrino physics and understand the origin of the high-energy astrophysical neutrino flux. Additionally, he has worked on searching for signatures of new physics using the large sample of IceCube atmospheric neutrino events. He is also involved in the development of the IceCube Upgrade, which will extend IceCube’s scientific capabilities to lower energies and enable more precise flavor identification of neutrinos.

In support of his experimental work, Argüelles also studies neutrino phenomenology, allowing him to be involved in the full arc of an experimental analysis, from initial idea to final result. His recent work includes calculating signatures of heavy neutrinos and neutrino–dark matter interactions. Currently, Argüelles is collaborating on a project to search for deviations from the expected behavior of neutrinos in the global neutrino data set.

“I am honored to receive this award,” said Argüelles. “I thank my mentors, my IceCube collaborators and friends, and my neutrino theory friends. For me, this award reflects the fact that we live in very exciting times to do neutrino physics and astrophysics. There is much to discover and learn ahead of us.”

Prof. Demler Awarded 2021 Hamburg Prize for Theoretical Physics

Prof. Eugene Demler was awarded this year's Hamburg Prize for Theoretical Physics by the Joachim Herz Foundation, the Wolfgang Pauli Centre, and the University of Hamburg.

The prize, which is awarded for outstanding research achievements in theoretical physics, goes to Demler for his work on quantum fluids and solids, and especially for his contributions to the study of ultracold atoms in optical lattices

“With Eugene Demler, we are honoring a researcher this year who has rendered outstanding services to the application of his theoretical work in experimental physics,” said Henneke Lütgerath, chairman of the executive board of the Joachim Herz Foundation. “His thoughts have provided many important impulses for the development of new materials.”

Demler is a highly original and creative theoretician with broad interests and outstanding expertise in different areas of modern condensed matter physics and quantum optics. He is a member of the Harvard-MIT Centre for Ultracold Atoms and the Institute for Theoretical Atomic Molecular and Optical Physics at the Harvard-Smithsonian Center for Astrophysics.

Other awards Demler has won include the 2006 Johannes Gutenberg lecture award from the Mainz Graduate School, and the Humboldt Research Award in 2015. That same year, he was elected as a fellow of the American Physical Society and became a Distinguished Scholar at the Max Planck Institute for Quantum Optics in Garching near Munich. He is currently a visiting Professor in the Physics Department at ETH Zurich.

The main focus of Demler's work has been understanding collective properties of quantum matter across many microscopic systems. His work has had impact on areas ranging from quantum magnetism to superconductivity, nonlinear quantum optics, quantum simulators based on ultracold atoms, and pump and probe experiments in solids.

“The rapid progress in the field of quantum simulators came from close collaboration between theory and experiment,” Demler said. “Cold atom experiments have revealed many new physical phenomena already, but the field stays as dynamic and exciting as in its early stages. I am grateful to the experimental physicists at Harvard and around the world for many stimulating discussions and fruitful collaborations. And most of all, I am grateful to several generations of students and postdocs in my group, who should really get all the credit for the work recognized by the Herz foundation. They were equally enthusiastic about pursuing pie in the sky theoretical ideas and understanding the nitty-gritty of experiments.”

The Hamburg Prize for Theoretical Physics has been awarded to researchers since 2010 and is one of the most highly endowed physics prizes in Germany.

Demler will accept the prize at the Hamburg's physics institutions international symposium in November.

Kang-Kuen Ni Promoted to Full Professor with Tenure

Congratulations to Prof. Kang-Kuen Ni on her promotion to Professor of Chemistry and Chemical Biology and of Physics, with tenure, effective July 1, 2021!

Ni left Taiwan in 2000 for the University of California, Santa Barbara, where she obtained her B.S. in physics and later earned her Ph.D. in physics from the University of Colorado, Boulder. She joined Harvard’s Chemistry and Chemical Biology Department in 2013. Her research is focused on creating molecules at the lowest possible temperatures and studying their chemical reactions and physical interactions.  Currently, her group is pursuing three research projects: Ultracold Molecular AssemblerUltracold Chemical Reactions, and Dual-species Atom Quantum Simulator.
