  • A Weyl semimetal formally requires either broken time reversal symmetry or inversion symmetry. One class of Weyl semimetals-the crystal family of NdAlSi-exhibits both. Here, Li et al perform angle-resolved photoemission spectroscopy measurements on NdAlSi, and observe the formation of an additional Weyl fermion as the material becomes ferrimagnetic.

  • Here, the authors investigate the interfacial charge/energy transfer dynamics in a WSe2/graphene heterostructure. They unveil an energy transfer mechanism from WSe2 to graphene mediated by an interfacial Meitner-Auger process, resulting in a transient hole distribution in the Dirac cone at energies larger than the photon energy of the optical excitation.

  • A computational workflow centered on probabilistic machine learning is developed to reconstruct the energy dispersion from photoemission band-mapping data. The workflow uncovers previously inaccessible momentum-space structural information at scale.
