Relation Between the Spin Hall Conductivity and the Spin Chern Number for Dirac-like Systems
Ömer F. Dayi, Elif Yunt
A semiclassical formulation of the spin Hall effect for physical systems satisfying Dirac-like equation is introduced. We demonstrated that the main contribution to the spin Hall c…

Effective field theory of topological insulator and the Foldy-Wouthuysen transformation
O. F. Dayi, M. Elbistan, E. Yunt
Employing the Foldy-Wouthuysen transformation it is demonstrated straightforwardly that the first and second Chern numbers are equal to the coefficients of the 2+1 and 4+1 dimensio…

Gauge Potential Formulations of the Spin Hall Effect in Graphene
O. F. Dayi, E. Yunt
Two different gauge potential methods are engaged to calculate explicitly the spin Hall conductivity in graphene. The graphene Hamiltonian with spin-orbit interaction is expressed…
