Spin Currents of Charged Dirac Particles in Rotating Coordinates
O. F. Dayi, E. Yunt
The semiclassical Boltzmann transport equation of charged, massive fermions in a rotating frame of reference, in the presence of external electromagnetic fields is solved in the re…
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…
3+1 dimensional topological field theory as the effective action of neutral fermions
O. F. Dayi, M. Elbistan
We proposed an action of neutral fermions interacting with external electromagnetic fields to construct a 3+1 dimensional topological field theory as the effective action attained…
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…
An Alternative Formulation of Hall Effect and Quantum Phases in Noncommutative Space
O. F. Dayi, B. Yapiskan
A recent method of constructing quantum mechanics in noncommutative coordinates, alternative to implying noncommutativity by means of star product is discussed. Within this approac…
