SX-ARPES measurements, which are reasonably bulk sensitive, reveal the 3D linearly dispersive bulk Weyl cones and Weyl nodes. Furthermore, by combining the low –photon-energy and SX-ARPES data, we show that the locations of the projected bulk Weyl nodes correspond to the terminations of the Fermi arcs within our exper-imental resolution.

Near the edge the gap is partially filled compared to the bulk, indicating conduction in

Au(111) data recorded with DA30-L, 2D Ferrum VLEED detector, the VUV5k UV source and using the analyser deflector capability for ARPES and Spin mapping. The complete ARPES data cube was recorded in 10 min and the high resolution Spin measurement to the right was recorded in 2 h, all with fixed sample/manipulator position. In the future, analysis using the more-sophisticated DMFT will be needed to fully explain the details of the experimental data and to provide a new explanatory mechanism for the metal–insulator transition in V 2 O 3.

To characterize a single magnetic domain picture, we resort to the calculations and scrutinize the interplay of the Rashba spin-orbit coupling field with the in-plane exchange field, provided by the ferromagnetically ordered $4f$ moments of the near-surface Gd layer.

The energy distribution of the conducting and valence band electrons can be derived from these data. The surface remains conductive at very low temperature (1 K).

Importing ARPES data. At the moment, this module can only import data produced by Scienta-Omicron SES program. For the Spectral scans, we will use the plaintext (.txt) files as input, and in case of Fermi map data, we will need the ZIP files as input.
We store bandstructure data in both Igor and plain text formats, while the Fermi mapping data is stored in a zipped binary format. The data can be easily opened by Igor program, or our arpespythontools package can be used analyze the ARPES is a photon-in electron-out spectroscopy based on the photoelectric effect. An incoming photon, generated in x-ray sources or laser systems, is directed at a sample where it is absorbed.
