Variation of (a) up and (b) down spin energy levels as a function of AB flux ϕ, considering a bigger ring with N = 200. The energy levels described by the light green color have finite slopes with ϕ, while the rest of the energy levels represented by the black color are completely flat (zero slope). Here we choose the asymmetric hopping condition t 1 < t 2 (t 1 = 1, t 2 = 1.5). The spin dependent scattering parameter h is fixed at 1.

In this work we report for the first time the appearance of non-decaying circular spin current in a magnetic ring with vanishing net magnetization, even in absence of any spin chirality. Breaking the symmetry in hopping integrals we can misalign up and down spin electronic energy levels which yields a net spin current in the magnetic quantum ring,...

A magnetic field can generally induce circular phonon dichroism based on the formation of Landau levels of electrons. Here, we study the magnetization-induced circular phonon dichroism in transition metal dichalcogenides, without forming Landau levels. We find that, instead of the conventional deformation potential coupling, pseudogauge-type electr...
