Along the domain wall, the rotors polarize in opposite directions, causing the electron to localize along a particular lattice direction. The rotor-electron coupling is identified as the origin of a structural instability in the crystal that leads to the domain-wall formation via a symmetry-breaking process. Our results provide the first theoretical description of ferroelectric polarons, as discussed in the context of soft semiconductors. https://research-explorer.ista.ac.at/download/19437/19461/2025_PhysReviewLetters_Kluibenschedl.pdf application/pdfno American Physical Society2025 eng 0031-9007 1079-7114 2407.19993 40131090 00149280880001010.1103/PhysRevLett.134.096302 1349 Kluibenschedl, Florian, Georgios Koutentakis, Ragheed Al Hyder, and Mikhail Lemeshko. “Domain-Wall Ferroelectric Polarons in a Two-Dimensional Rotor Lattice Model.” <i>Physical Review Letters</i>.
