Winding charge density wave: intertwining of structural chirality and phase topology of electronic order
Shun Asano, Youichi Yanase
We propose a class of chiral charge density waves (CDWs), dubbed winding CDWs, that exhibit macroscopic chirality despite a single ordering wavevector. In screw-symmetric chiral cr…

Spontaneous spin-selective structural phase transition in chiral crystals
Shun Asano, Youichi Yanase
In this Letter, we predict a structural phase transition unique to chiral crystals with screw symmetry. In chiral crystals, the phonon frequency renormalized by the electron-phonon…
