Data and analysis scripts for: Domain-Selected Spin Projection and Orbital-Filling Softening of Charge Plasmons in a Model Altermagnetic RbV2Te2O Coulomb Bilayer

Version 2.0 (revision, Nanomaterials manuscript ID nanomaterials-4652174): adds the numerical data, logs and scripts of the revision calculations R_T1–R_T9: numerical convergence; position of the plasmons relative to the particle–hole continuum and peak widths; layer asymmetry from unequal filling and broadening; electron number and Rb-vacancy mapping with moderate carrier-density changes; Fermi-surface topology and temperature dependence; relative twist of the two layers; sensitivity to tight-binding parameters; absolute spin and charge spectral weights; layer-weighted detection.
