| contents | We investigate the transmission properties of a junction between a normal metal and a p-wave magnet in the ballistic regime. We introduce a two-dimensional square lattice that confirms the p-wave magnet criteria. The $α$-vector of the magnet breaks the inversion symmetry of the parabolic dispersion, shifting them in $k$-space. These shifts alter the propagation direction of fermions passing through the junction interface. Depending on spin orientation, the transmission process exhibits anisotropic, angle-dependent behavior. We also demonstrate a mirror symmetry between fermions with opposite spin directions, leading to the emergence of a transverse spin current that flows parallel to the interface. Additionally, we show that the $α$-vector acts as a source for the dynamics of the spin-density wave and observe the formation of an indirect gap in the conductance of the junction. Our findings highlight the unique transmission characteristics and spin transport phenomena in normal metal/p-wave magnet junctions, paving the way for potential applications in spintronic devices. |
