OverviewAI-generated summary
Laurent Bellaiche's research focuses on computational physics, particularly the study of ferroelectric and piezoelectric materials. He investigates phase transitions in ferroelectric nanostructures, exploring phenomena such as unusual phase transitions in ferroelectric nanodisks and nanorods. His work also includes examining the finite-temperature properties of alloys like Pb(Zr1−xTix)O3 from first principles and revisiting the virtual crystal approximation for perovskite properties.
Bellaiche has explored advanced applications of materials science, including the development of solid-state synapses for learning through ferroelectric domain dynamics. His research interests extend to quantum phenomena, such as the Quantum Anomalous Hall Effect in graphene and the manipulation of magnonic and spintronic responses in materials like BiFeO3 films through epitaxial strain. He has also studied the interplay of interactions in magnetic materials like CrI3 and CrGe3Te3 monolayers.
With a reported h-index of 3 and 602 total citations across 8 publications, Bellaiche actively collaborates with colleagues at the University of Arkansas at Fayetteville, including Sergei Prokhorenko, Yousra Nahas, S. A. Prosandeev, and Charles Paillard, with whom he shares numerous publications. He maintains an active laboratory website to disseminate his research.
