Data for "Geometry-Controlled Sign Reversal of Three-Body Polarization in Rotating-Field Colloids"

This record contains the processed numerical data and analysis scripts underlying the figures, tables, and quantitative results of the manuscript “Geometry-Controlled Sign Reversal of Three-Body Polarization in Rotating-Field Colloids.” The deposited data include the refined orientation-dependent pair-interaction map, corrected three-body self-consistent-multipole (SCM) maps, independent off-grid validation data, far-field r−6 diagnostics, and fixed-geometry N=4–6 cluster-validation results. The archive also contains the analysis and plotting scripts required to reproduce the principal numerical tests and publication figures. The calculations describe identical dielectric spheres in a quasistatic rotating electric field and isolate cycle-averaged dielectric polarization at fixed particle coordinates. The production SCM calculations use particle radius a=1.0μm, relative permittivities εp=3.9 and εs=81, field amplitude E0=105Vm−1, multipole cutoff lmax=6, eight field phases, and nquad=8000. The data support the orientation-dependent sign reversal of the nonadditive three-body polarization contribution, the connected-dipolar r−6 far-field asymptote, and the transfer of isolated-triplet corrections to independently generated N=4–6 clusters. The cluster results refer to the ordering of the calculated fixed-geometry polarization-energy functional and should not be interpreted as evidence of equilibrium morphology switching or as a direct determination of mechanical force directions. The trained ML3B surrogate model and refined SCM pair-interaction map are archived separately at Zenodo, DOI: 10.5281/zenodo.21512150. Source code, command-line tools, examples, and tests are maintained at the public GitHub repository vanyasimkin/rotating-field-three-body.
