Polarization Dynamics in Ferroelectrics: Insights Enabled by Machine Learning Molecular Dynamics

Advanced Science, EarlyView.
Machine learning molecular dynamics is presented as a route to capture polarization switching, domain wall kinetics, topological polar textures, and polar mechanical coupling beyond the limits of conventional atomistic methods. This Perspective surveys recent progress and identifies key methodological directions, including long‐range electrostatics ...

Twist phase in Gaussian-beam optics

Journal of the Optical Society of America A, 1998
The recently discovered twist phase is studied in the context of the full ten-parameter family of partially coherent general anisotropic Gaussian Schell-model beams. It is shown that the nonnegativity requirement on the cross-spectral density of the beam demands that the strength of the twist phase be bounded from above by the inverse of the transverse

Twist as a Probe for Phase Structure

Physica Scripta, 1981
Summary: We advocate the use of twist as an efficient tool, in computer simulated lattice gauge theories, for quick scan of phase diagrams and for determining phase structure. Physically, a twist is an excitation induced by a specific dislocation (`twisted boundary condition') in the system.
