Correlated one-dimensional electron conduction in ferroelastic domain walls through nematic-like charge stripes

One-dimensional electronic transport reveals many-body quantum phenomena and serves as a foundation for quantum devices, sensors, and reconfigurable electronics. Here, we demonstrate that surface-exposed ferroelastic twin walls in epitaxial WO 3 films function as intrinsic one-di...

Nanolayer-Confined Strain Waves in Femtosecond-Optical-Vortex-Excited Multiferroic BiFeO3

Abstract Strain waves provide a route to reshape nanoscale order in functional materials, where lattice deformation couples to charge and spin degrees of freedom. Real-space tracking of these transient strain fields is critical for connecting acoustic excitation to functionality,...
