Crystal growth and scattering of quantum materials
Crystal growth and scattering of quantum materials
Anyone who has visited a museum with an exhibit on minerals knows that nature can produce beautiful crystals. However, the crystals found in nature represent only a tiny fraction of what is possible using all the ingredients on the periodic table. Furthermore, the conditions in nature are far from pristine and these naturally occurring crystals, though beautiful, often have high levels of disorder or impurities at the atomic level. In the Hallas Lab, part of the Blusson Quantum Matter Institute at the University of British Columbia, we design and grow crystals of materials that are not found in nature. In particular, the Hallas Group seeks out materials with strong quantum mechanical effects, giving rise to exotic magnetic and electronic properties. We aim to understand the behaviors of these quantum materials by studying their properties with neutrons, muons, and x-rays.
May 2025: We are excited to officially welcome friend-of-the-lab Michelle Huang for summer undergraduate research!
April 2025: In the latest issue of Nature Physics, Alannah delves into the underrepresentation of women last authors and what we can do about it.
March 2025: Samikshya, Mario, Joern, Mohamed, and Dongjoon made the journey to sunny Anaheim to attend the APS Global Physics Summit.
February 2025: Alannah had a lot of fun delivering a keynote talk on the crystal growth of quantum materials on at Quantum Days in Toronto.
January 2025: A warm welcome to new PhD student Andree Coschizza, who will be working jointly with the Hallas and Ye labs.
Congrats to Valentina Mazzotti on publishing her Honour's thesis research. Check out her paper to learn why breathing pyrochlore distortions are so rare.
November 2024: Congrats to Mohamed on his new paper that explores electron-phonon coupling in LaRhGe3, available now in npj Quantum Materials.
October 2024: We're excited to welcome new postdoc Austin Ferrenti, who recently completed his PhD at Johns Hopkins University!
September 2024: Welcome to Allison Pavlik, who is doing her Chemistry Honours thesis research with the Hallas lab, and welcome back to Morgan Brand and Ksenia Khoroshun, who are doing their Physics Honours thesis.
Check out our two new papers on short-range order and synthesis method dependence in high entropy oxides. Congrats, Mario and Solveig!
July 2024: Alannah has been promoted to Associate Professor with tenure!
June 2024: The group is kicking off a busy summer of beam time experiments. This month, Mario is traveling to Diamond for x-ray absorption, in July, Megan and Ashutosh will visit the Spallation Neutron Source for single crystal diffraction, and in August, Samikshya, Ashutosh, and Alannah will visit PSI for a marathon of three neutron experiments. We're also indulging in a healthy dose of muons locally!
May 2024: We are excited to welcome three new undergraduate researchers, Helena Nunez, Gannon Munro, and Ksenia Khoroshun to the lab for a summer of crystal growth. We are also excited to welcome back Valentina Mazzotti who will continue to computationally explore the stability of breathing pyrochlores.
April 2024: The group is taking a short drive down the coast to attend the MRS meeting in Seattle. Alannah is an organizer for the high entropy materials symposium, Solveig will be delivering an invited talk, and Mario will be competing for a student prize.
Valentina Mazzotti has completed her Honours thesis and is graduating from UBC. Congratulations Valentina!
March 2024: Alannah and Brad Ramshaw (Cornell) will join Leon Balents (UCSB) as the new Co-Directors of the CIFAR Quantum Materials Program.
January 2024: A warm welcome to Ashutosh Kumar Singh, who is joining the lab after completing his PhD at JNSCAR. Ashutosh is the recipient of UBC's prestigious Killam Postdoctoral Fellowship. Welcome and congratulations Ashutosh!
