Weyl semimetals resulting from either inversion ( P ) or time-reversal ( T ) symmetry breaking have been revealed to show the record-breaking large optical response due to intense Berry curvature of Weyl-node pairs. Different classes of Weyl semim...
We have observed an extremely largemagnetoresistance exceeding 1.9 million at 1.7Kat 40 T for a single crystal of the binary semimetal NbAs2. The magnetoresistive behavior for this compound is quantitatively reproduced by a semiclassical two-carri...
