The Lars Onsager Lecture and Professorship
Lars Onsager (1903–1976)
Norwegian-American chemist and physicist. Born in Oslo, Ch.E. degree from Norges Tekniske Høiskole, Trondheim, in 1925. Emigrated to the USA in 1928 and became an American citizen in 1945. J. Willard Gibbs Professor at Yale University. Received the 1968 Nobel Prize in Chemistry for work done in 1931 on irreversible thermodynamics. (Biographical note).
The Lars Onsager Lecture and the Lars Onsager Professorship are awarded by the Onsager committee.
Present Onsager Professor – Jian-Min Zuo
The Lars Onsager Professorship for 2017 has been awarded to Professor Jian-Min Zuo, Professor of Materials Science and Engineering at University of Illinois at Urbana-Champaign, USA.
Jian-Min Zuo presents the lecture with title Topological Defects in Mesoscopic and Complex Crystals on Friday, March 24, at 14:15 in Realfagbygget R10, as part of the Physics Friday Colloquia. On this occasion he will be presented with the Onsager medal.
Abstract: Recent experiments have revealed new forms and new dynamics of topological defects in mesoscopic and complex crystals, such as flux-closure ferroelectric vortices in oxide superlattices, magnetic skyrmions in thin-films, dislocations and grain boundaries in graphene. At the same time, the development of new multiple components materials, such as high entropy alloys, challenges our traditional understanding of crystal defects and presents opportunities for the discovery of new physics. In this talk, I will describe how the development of electron microscopy has enabled the study of topological defects in mesoscopic and complex crystals. Two examples will be highlighted, one is vortices in ferroelectric crystals and the other is dislocation dynamics in high entropy alloys; their observation represents the success stories of modern transmission electron microscopy.
The Lars Onsager archive
Thanks to the generosity of Lars Onsager's sons and daughter, the Norwegian University of Science and Technology has established a Lars Onsager archive located at NTNU Library/Gunnerus Library in Trondheim.
A substantial part of the archive has now been made freely available in digital form.
