Abstract: In this work we investigate the electronic, optical, dynamic and thermoelectric properties of ternary copper-based Chalcogenides CuSbX2 (X= S, Se) compounds. Calculations are based on density functional theory and the semi-classical Boltzmann theory. Computations have been carried out by using Quantum-Espresso (PWSCF) package and ab-initio pseudo-potential technique. To estimate the e...

although electronic contract consists of offer and acceptance, its specific characteristics and the fact that parties to it state their intention in a virtual world i.e. cyber-space, and specially given consumer's need of enough protection in this environment, new rules have been included in laws concerning this kind of contract which seek to make sure that consumer has been well informed ...

We study the electronic structure near impurities in the d-density-wave (DDW) state, a possible candidate phase for the pseudogap region of the high-temperature superconductors. We show that the density of states near a nonmagnetic impurity in the DDW state is qualitatively different from that in a superconductor with dx(2)(-y(2)) symmetry. Thus, the electronic structure near impurities can pro...

in the present work, we have examined the ability of some different equations of state in predicting the joule-thomson coefficient, ?j-t, of different fluids. for dense fluids, for which density is greater than the boyle density, ?b, two appropriate equations of state, namely the linear isotherm regularity, lir, and the dense system equation of state, dseos, have been examined. the results show...

We have developed a comprehensive modeling network for a millisecond pulsed glow discharge in argon (Ar) with copper (Cu) cathode, to describe the behavior of the various plasma species. Typical results of the model are shown, such as the potential distribution during and after the pulse, the densities of Ar ions, Ar atoms in the metastable and various other excited levels, Cu atoms and Cu ions...

in this paper, using the tight-binding model, we extend the real-space renormalization group method to time-dependent hamiltonians. we drive the time-dependent recursion relations for the renormalized tight-binding hamiltonian by decimating selective sites of lattice iteratively. the formalism is then used for the calculation of the local density of electronic states for a one dimensional quant...

In the multiband systems, Hund's coupling ($J$) plays a significant role in spin and charge excitations. We study dependence of electronic anisotropy on $J$ terms Drude-weight along different directions as well orbital order four-fold symmetry broken spin-density wave state iron pnictides. A robust behavior within small window around $J \sim 0.25U$ with $U$ intraorbital Coulomb interaction is d...
