Brown-Zak oscillation analysis in graphene superlattices. Computes Δ(1/B), wavelength, and twist angle via linear regression.

Bidirectional: nₛ → twist angle and angle → nₛ. Computes moiré wavelength for twisted 2D materials.

Spring constant calibration (k_cant), deflection, and force calculation from AFM frequency and voltage readings.

Transform sample coordinates between coordinate systems using two reference points and a new basis.

Estimate top/bottom gate capacitance from hBN thickness using parallel-plate model C = ε₀·εᵣ/d. Input BN thickness (nm) and relative dielectric constant.

Stack hexagonal graphene lattices rotated by θ and watch the moiré superlattice emerge. Explore the magic angle (≈1.1°) behind twisted-bilayer superconductivity. Exportable as PNG or SVG.

Post-processing of quantum anomalous Hall (QAH) transport data. Handles B-sweep, n-sweep, and D-sweep datasets. Extracts Rxx via field-symmetrization and Rxy via field-antisymmetrization protocols.
