Time-Reversal-Breaking Weyl Fermions in Magnetic Heusler Alloys
Time-Reversal-Breaking Weyl Fermions in Magnetic Heusler Alloys
Weyl fermions have recently been observed in several time-reversal-invariant semimetals and photonics materials with broken inversion symmetry. These systems are expected to have exotic transport properties such as the chiral anomaly. However, most discovered Weyl materials possess a substantial number of Weyl nodes close to the Fermi level that give …
