Weyl semimetals are topological materials whose low-energy excitations obey the Weyl equation. In a Weyl semimetal, the conduction and valence bands touch at discrete points in momentum space called ...

Researchers have demonstrated an ideal Weyl semimetal, marking a breakthrough in a decade-old problem of quantum materials. An international team of researchers led by the Strong Correlation Quantum ...

We present a study of Rainich-like conditions for symmetric and trace-free tensors T. For arbitrary even rank we find a necessary and sufficient differential condition for a tensor to satisfy the ...
