The interplay between time-reversal symmetry (TRS) and band topology plays a crucial role in topological states of quantum matter. In time-reversal-invariant (TRI) systems, the inversion spin-degenerate bands with opposite parity leads to nontrivial states, such as insulators Dirac semimetals. When TRS is broken, exchange field induces spin splitting bands. pair spin-splitting subbands can generate more exotic anomalous Hall magnetic Weyl So far, phase transitions driven by breaking have not...
