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…

Quasiclassical theory of vortex states in locally non-centrosymmetric superconductors: application to CeRhAs
Akihiro Minamide, Youichi Yanase
CeRhAs, a heavy fermion superconductor discovered in 2021, exhibits two distinct superconducting phases under a -axis magnetic field. This unconventional phase diagr…

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…
