Evaluation of vorticity expansion approximation of current-density functional theory by means of Levy’s asymptotic bound
The density functional theory DFT provides a powerful and reliable approach to the electronic structures of manyelectron systems.1,2 The DFT has been extended so that various physical quantities can be chosen as basic variables.3–5 For instance, the spin-density functional theory,6,7 the current-density functional theory CDFT ,8–11 and LDA+U method12–15 are regarded as examples of such extensio...
متن کاملVorticity expansion approximation of the exchange-correlation energy functional in current density functional theory
We propose the vorticity expansion approximation VEA formulas of the exchange and correlation energy functionals of the current density functional theory CDFT . They have a form of the second-order expansion with respect to the vorticity. Expansion coefficients are determined by requiring them to satisfy exact relations that have been derived from scaling properties of exchange and correlation ...
متن کاملthe effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
