报告人简介:
George Sawatzky is a Canadian physicist known for pioneering work on strongly correlated electron systems. He co-developed the Cini-Sawatzky theory of the Auger effect and the Zaanen-Sawatzky-Allen (ZSA) bandgap classification. A professor at the University of British Columbia, he has received the Spinoza Prize, the Henry Marshall Tory Medal, and is a Fellow of the Royal Society (London) and the Royal Society of Canada.

报告摘要:
3d transition metal and rare earth compounds continuously reveal exotic properties like high-temperature superconductivity, hard magnets, ion batteries, large thermoelectric effects, dissipationless spin transport, altermagnets, and topological insulators. I will explain why these elements retain much atomic character in solids, leading to strong electron correlations that challenge our understanding of electronic, magnetic, and crystallographic structures. Focusing on Cu and Ni oxides (including high-Tc superconductors), I will use exact diagonalization of small clusters and hybrid density functional theory to show strong spin-charge-lattice interplay. This also leads to a new electron-boson coupling, where bosons are local singlet-triplet excitations distinct from conventional magnons.
