A k · p Effective Hamiltonian Generator

$k\cdot p$ effective Hamiltonian is important for theoretical analysis in condensed matter physics. Based on the 'kdotp-symmetry' package, we develop an upgraded package named 'kdotp-generator'. This generator takes arbitrary magnetic symmetries with their representations and returns symmetry-allowed Hamiltonians. Using this calculate Hamiltonians irreducible corepresentations 1651 space groups up to third order, linear coupling external fields including electromagnetic field strain tensor. We hope that will facilitate related research future.
