OverviewAI-generated summary
Yousra Nahas's research focuses on the study of topological phases in polar oxide nanostructures and ferroelectric thin films. Her work investigates the emergence and behavior of exotic magnetic and electric states, such as skyrmions and bubble domains, at the nanoscale. Nahas has published on the discovery of stable skyrmionic states in ferroelectric nanocomposites and the topological spin textures in two-dimensional materials like chromium trihalides.
Her research explores phenomena such as the inverse transition of labyrinthine domain patterns in ferroelectric thin films and the nanoscale bubble domains and topological transitions observed in ultrathin ferroelectric films. She has also investigated the potential for Kitaev quantum spin liquid states in 2D materials with a spin of S=3/2. Nahas collaborates with researchers at the University of Arkansas at Fayetteville, including Sergei Prokhorenko and Laurent Bellaiche, with whom she shares numerous publications.
With a career marked by 95 publications and over 2,740 citations, Nahas holds an h-index of 25. Her recent work includes a 2023 publication on topological phases in polar oxide nanostructures and a 2022 publication on high-density switchable skyrmion-like polar nanodomains integrated on silicon. She is listed as recently active, with her most recent publication in 2026.
