The focus of a scalar vortex beam results into a transverse-axial polarization vector texture around the phase singularity, mapped from Gauss-Stokes Poincaré sphere, and forming a skyrmion. In ...
Figure 1:Magnetic-field-driven superconductor-metal phase transition with multiple quantum critical points in CaFe 1-x Ni x AsF. Exploration of exotic quantum phase transitions has always been a focus ...
