Present paper dealswith the calculation of electrical resistivity (ρ) of Ni-Cr liquid binary alloy using Faber-Ziman formulation. Todescribe electron-ion interaction we have used newly constructed parametricfree model potential along with Ashcroft-Langreth (AL) partial structurefactor. To see the influence of exchangeand correlation effect, Hartree, Taylor and Sarkaret allocal field correlation functions are used. From presentresults, it is seen that good agreements between present results andexperimental data have been achieved. Lastly we conclude that our model potential successfully produces thedata of electrical resistivity (ρ) ofNi-Cr liquid binary alloy.

Liquid Binary Alloy

Electronic transport property like electrical resistivity (ρ) of Co-Cr liquid binary alloy is calculated using Faber-Ziman formulation. To describe electron-ion interaction we have used newly constructed parametric free model potential along with Ashcroft-Langreth (AL) partial structure factor. To see the effect of exchange and correlation effect on electrical resistivity, we have used different local field correction functions like Hartree, Taylor and Sarkar et al. From present results, it is seen that good agreements between present results and experimental data have been achieved. Lastly we conclude that our model potential successfully produces the data of electrical resistivity (ρ) of Co-Cr liquid binary alloy.

The thermodynamic properties like heat of mixing (ΔE), entropy of mixing (ΔS) and volume of mixing (ΔΩ) of Fe-Co liquid binary alloys are computed using our newly constructed parameter free model potential. We have also attempted to investigate the effect of various forms of exchange and correlation functions, namely, Hartree (H) and Taylor (T) on the thermodynamic properties of Fe-Co liquid binary alloys. It is found that the proper choice of the model potential along with the local field correction function play an important role in investigating the thermodynamic properties of Fe-Co liquid binary alloys.

Two Parameters

Liquid K_(1-x) Rb_x binary alloys with various thermodynamical proportions of participating elements are investigated. The properties of thermodynamic interest are included in the study. The internal energy (Fint), Helmholtz free enrgy (FH) and the entropy (S) have been calculated in a concentration range from X=0.0 to X=1.0 increasing in a step of 0.1 in the present work. Apart from the internal energy (Fint), various contributions to this energy are also calculated and separately depicted in the present article. A variational approach has been adopted for the present calculation. A single potential with a set of two parameters is used for the calculation of all properties of the alloys. Static Hartree local field function (H) is used to consider screening effect. Various local field correction functions are used to take into account the exchange and correlation effect. Comparison with experimental data at some concentration shows the good agreement with the presently obtained data. With the help of current results, the applied model potential found very suitable with individual parameters for thermodynamical study. As the present results provide the data even where minimum availability of the experimental findings, it can serve as a data base for the future calculation which deals with thermodynamics of the liquid alloys. Present results allow one to get proportion based tuned properties of the K_(1-x) Rb_x for different requirements.

We show the calculation of the monovacancy formation energy ( v FH E1 ) for three different group-I monovalent fcc metals (Cu, Ag and Au) and two group-IV tetravalent fcc metals (Pb and Th) use a pseudopotential approach. Ashcroft's empty core model potential (AECMP) and nine different exchange and correlation functions (ECF) are used. The variation of v FH E1 with the parameter c r of AECMP for different ECF shows variations with the metals, and c r is observed to be greater than Bohr radius.

Twist Fields

The three-point correlation functions with twist fields are determined for bosonic ZN orbifolds. Both the choice of the modular background (compatible with the twist) and of the (higher) twisted sectors involved are fully general. We point out a necessary restriction on the set of instantons contributing to twist field correlation functions not obtained in previous calculations. Our results show that the theory is target space duality invariant.
