Using Photocurrents to Control the Symmetry of a Weyl Semimetal Optically driven photocurrents can break the electronic symmetry in a Weyl semimetal
Topological Quantum Switching via Light-Driven Raman Coherence (CATS) A topological switching principle is established by periodically driven, Raman phonon oscillations.

Spin-to-charge conversion in a magnetic Weyl semimetal The unique topological band crossings in the magnetic Weyl semimetal controls the spin-to-charge conversion. This provides novel pathways to manipulate the effect and can be exploited in potential applications in quantum materials.
Fractional Quantum Hall Effect in Weyl Semimetals Strong electron-electron interactions can give rise to an energy gap without breaking crystal translational symmetry. This leads to a unique state, a 3D version of nonabelian 2D fractional quantum Hall liquids. The properties of this exotic state may be useful in quantum computing applications.
