With reference to chiral electronics and topological semimetals, which of the following statements is correct?
- 1Chiral separation of electrons in solids necessarily requires strong external magnetic fields to induce handedness-dependent transport.
- 2In topological semimetals, electronic chirality refers to classical spin alignment under applied electric fields.
- 3Palladium gallium (PdGa) crystals exhibit centrosymmetric lattice geometry that suppresses chiral electronic transport.
- 4Quantum geometry of certain non-centrosymmetric crystals can enable chirality-dependent current separation.✓
Correct answer
Quantum geometry of certain non-centrosymmetric crystals can enable chirality-dependent current separation.
