We have discussed the gauge invariance of nonlinear Klein-Gordon equation which describes the interaction of electromagnetic initially proposed by Hermann Weyl. The construction of nonlinear Klein-Gordon itself is formulated by two classical conserva

The density functional theory was utilized to investigate the likelihood of a tunable magnetic state in the AA-stacked bilayer zigzag graphene nanoribbon. The non-magnetic ground states at certain thicknesses were found, but then the magnetic ground

The electronic properties of FeCl2 monolayer were inspected by using the LDA+U approach and including the spin-orbit interaction. By observing the band dispersion, it was shown that the metallic state changes to the insulating state by increasing the

We implemented the density functional theory to study the effect of strain on the optical conductivity in 1T monolayer FeCl2 within the collinear structure. The computational calculation was run based on the Kubo-Greenwood formulation. We showed that

The density functional theory was employed to the non-collinear magnetic calculations to consider the impact of spin-orbit interactions and external electric field on the NiBr2 monolayer. It was shown that spin-orbit interaction reduces the energy ga

Considering a set of condensates as N indistinguishable noninteracting quantum oscillators and replacing an available volume with a harmonic volume, we derived an ideal gas model by applying the canonical partition function via the thermodynamic rela

We considered the effect of the electric field on the spin stiffness in the zigzag graphene nanoribbon by means of first-principles calculation. To reach the intention, a fixed planar spiral structure was formed together with a spin constraint method

We demonstrated the dependence of the phase transition in the one-dimensional hydrogen chain on the basis orbitals, the cut off radius, and the doping. For reducing the computational cost, we employed the so-called generalized Bloch theorem, where a
