Two-chain spin ladder with frustrating second-neighbor interactions
The Heisenberg model on a two-chain spin1 2 ladder with frustrating second-neighbor interactions is studied by using series expansions about the Ising and dimer limits, numerical diagonalization, and by Abelian bosonization analysis. The phase diagram is determined, and pair correlations and the complete dispersion relations for the triplet spin-wave excitations are also computed. @S0163-1829~9...
متن کاملA mean field theory for the spin ladder system
In the present paper, we propose a mean field approach for spin ladders based upon the Jordan-Wigner transformation along an elaborately ordered path. We show on the mean field level that ladders with even number legs open a energy gap in their low energy excitation with a magnitude close to the corresponding experimental values, whereas the low energy excitation of the odd-number-leg ladders a...
متن کاملAntiferromagnetic Spin Chain with Bond Alternation
i(1 − (−1)δ)Si · Si+1 by the density matrix renormalization group method recently proposed by Steven R. White (Phys. Rev. Lett. 69 (1993) 3844). We find a massless point at δc = 0.25 ± 0.01. We also find the edge states in the region δ < δc under the open boundary condition, which disappear in the region δ > δc. At the massless point, the spin wave velocity vs is 3.66 ± 0.10 and the central cha...

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...
15 صفحه اولThe Geometric Chain - Ladder
The log normal reserving model is considered. The contribution of the paper is to derive explicit expressions for the maximum likelihood estimators. These are expressed in terms of development factors which are geometric averages. The distribution of the estimators is derived. It is shown that the analysis is invariant to traditional measures for exposure.
