Machine-learning approach to understanding ultrafast carrier dynamics in the three-dimensional Brillouin zone of PtBi_{2}

Machine-learning approach to understanding ultrafast carrier dynamics in the three-dimensional Brillouin zone of PtBi_{2}

Using time- and angle-resolved photoemission spectroscopy, we examine the unoccupied electronic structure and electron dynamics of the type-I Weyl semimetal PtBi_{2}. Using the ability to change the probe photon energy over a wide range, we identify the predicted Weyl points in the unoccupied three-...
