▲ Abstract： Multifold topological semimetals host fermions with opposite chiralities at topological band crossings. Chiral fermionic transport in topological systems often relies on high magnetic fields or magnetic dopants to suppress trivial transport and create an imbalance in occupancy of opposite Chern-number states. Here we use the quantum geometry of topological bands to filter fermions by chirality into distinct Chern-number-polarized states. This allows for the real-space separation of currents with opposite fermionic chiralities。
