Fig. 2: Energy dispersion and Edelstein response for nodal p-wave minimal model.
From: Highly efficient non-relativistic Edelstein effect in nodal p-wave magnets
a Schematic of the lattice model with a coplanar non-collinear spin arrangement on the crystal with the spin arrangement that realizes the unconventional p-wave phase. The unit cell is marked with dashed green line. b Energy dispersion for tJ = 0.25 t along high-symmetry momentum paths showing parity broken time-reversal symmetric spin splitting. The color represent the out-of-plane spin component. The opposite spin bands are completely degenerate along the ky direction forming a nodal line. c Constant energy E = 3.1t contour with tJ = 0.25 t. d Variation of the NREE response for fixed Γ = 0.01 eV with the strength of the exchange term. An increase of tJ enhances the shifting of opposite spin bands in opposite momentum directions, therefore, the response strength χS increases.
