Smith, Hong Liu, Dimitrie Culcer et al.arXiv preprint·2024·10.1103/physrevlett.121.087701·arXiv:2412.02067AbstractWe numerically model transverse magnetic focusing in a two-dimensional hole gas (2DHG) within a GaAs/AlxGa₁-xAs heterostructure using a 4×4 Luttinger Hamiltonian and Kwant-based transport calculations. The calculations show heavy- and light-hole mixing at finite wave vector, demonstrate that Rashba-split heavy-hole subbands are not spin-polarized, and analyze conductance spectra under quantum point contacts, disorder, and with Rashba coupling turned off.Read more
