Enhanced Valley Polarization via Nonlinear Cascaded Quantum-Geometric Selection Rules

These datasets contain experimental time-, polarization- and angle-resolved photoemission spectroscopy (trARPES) measurements on 2H-MoTe₂, as well as corresponding theoretical simulations and calculations based on the time-dependent Lindblad master-equation formalism. They support the findings reported in the manuscript: Courtade et al., Enhanced Valley Polarization via Nonlinear Cascaded Quantum-Geometric Selection Rules.
