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.
September 2025: It's back-to-school season and the group is excited to welcome new Chemistry PhD student Karl Tsang and Physics MSc student Lex Rouquette. We're equally excited that recent MSc grad Abraham Mancilla is sticking around for a PhD 🥳
August 2025: This month, Ashutosh travelled to Ames, Iowa to give a talk at the NASSCC and Alannah gave a talk at an ICTP Workshop in Trieste, Italy.
May 2025: We are excited to officially welcome friend-of-the-lab Michelle Huang for summer undergraduate research! This month, Austin and Alannah attended the Highly Frustrated Magnetism Conference in Toronto!
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!
