Scaling theory of the Kondo screening cloud

Scaling theory of the Kondo screening cloud.

A scaling form for the local susceptibility, derived from renormalization group arguments, is proposed. The scale over which the uniform part of this scaling form varies can be viewed as a definition of the Kondo “screening cloud” ∼ ξK . The proposed scaling form interpolates between Ruderman-KittelKasuya-Yosida (RKKY) results in the high temperature limit, T ≫ TK , and Fermi liquid results in ...

the analysis of the role of the speech acts theory in translating and dubbing hollywood films

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...

Scaling theory of magnetic ordering in the Kondo lattices with anisotropic exchange interactions

The lowest-order scaling consideration of the magnetic state formation in the Kondo lattices is performed within the s−f model with inclusion of anisotropy for both the f − f coupling and s − f exchange interaction. The Kondo renormalizations of the effective transverse and longitudinal s − f coupling parameters, spin-wave frequency, gap in the magnon spectrum and ordered moment are calculated ...

Quantitative Calculation of the Spatial Extension of the Kondo Cloud

The internal s-electron polarization in the ground state of a Friedel-Anderson and a Kondo impurity is calculated. The Wilson basis with exponentially fine energies close to the Fermi level is used and expressed in terms of free electron waves with linear energy-momentum dispersion. It is found that in the singlet state the magnetic moment of the d-electron is screened by an s-electron cloud. T...
