Tuning Electronic Structures through Strain (CATS)
Tuning Electronic Structures through Strain
A topological switching principle is established by periodically driven, Raman phonon oscillations.
Time-dependence of such periodic driving is revealed which is needed for topological transistors and THz quantum gate applications.
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.
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.
