A Programmable k · p Hamiltonian Method and Application to Magnetic Topological Insulator MnBi2Te4

“…Therefore, it is practicable and highly necessary to develop automated programmable methods to efficiently construct 𝑘•𝑝 Hamiltonians. In this context, there have been some innovative proposes, such as kdotp-symmetry code developed by Gresch et al, [14,15] Qsymm Python package developed by Varjas et al [16,17] In this Letter, based on group theory, we independently develop a programmable algorithm to construct 𝑘•𝑝 Hamiltonians for all one-/two-/three-dimensional materials (the open-source code can be download from https://github.com/ shimj/Model-Hamiltonian). With this automated algorithm, only the crystal symmetry and atomic orbitals involved are needed to produce the 𝑘•𝑝 Hamiltonian, which effectively avoids time-consuming calculations and latent mistakes.…”
