چکیده

In this work, the order parameter or average magnetization expressions are obtained for square and honeycomb lattices based on recently relation, $<\sigma_{0,i}>= <\!\!\tanh[ \kappa(\sigma_{1,i}+\sigma_{2,i}+\dots +\sigma_{z,i})+H]\!\!> $. Where, $\kappa$ is coupling strength $z$ number of nearest neighbors. $\sigma_{0,i}$ denotes central spin at $i^{th}$ site while $\sigma_{l,i}$, $l=1,2,\dots,z$, neighbor spins around spin. our investigation, inevitably we have to make a conjecture about three correlation function appearing in relation paper. The conjectured form given by $<\!\!\sigma_{1}\sigma_{2}\sigma_{3}\!\!>=a<\sigma>+(1-a)<\sigma>^{(1+\beta^{-1})}$, here $\beta$ critical exponent $a$ positive real less than one. relevance fundamental physical reasoning. addition, it tested investigated comparing relations paper with previously exact results lattices. It seen that agreements those unprecedentedly perfect.

the search for the self in becketts theatre: waiting for godot and endgame

this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...

Exact spin liquid ground states of the quantum dimer model on the square and honeycomb lattices.

We study a generalized quantum hard-core dimer model on the square and honeycomb lattices, allowing for first and second neighbor dimers. At generalized Rokhsar-Kivelson points, the exact ground states can be constructed, and ground-state correlation functions can be equated to those of interacting (1+1)-dimensional Grassmann fields. When the concentration of second neighbor dimers is small, th...

Complex - temperature singularities in the d = 2 Ising model : triangular and honeycomb lattices

We study complex-temperature singularities of the Ising model on the triangular and honeycomb lattices. We first discuss the complex-T phases and their boundaries. From exact results, we determine the complex-T singularities in the specific heat and magnetization. For the triangular lattice we discuss the implications of the divergence of the magnetization at the point u = − 3 (where u = z2 = e...

The effect of material nonlinearity on the band gap for TE and TM modes in square and triangular lattices

In this article, by using the method of finite difference time domain (FDTD) and PML boundary conditions, we have studied the photonic band gaps for TE and TM modes in square and triangular lattices consisting of air holes in dielectric medium and compared the results. In addition, the effect of nonlinearity of the photonic crystal background on the photonic band gaps and comparison with the re...
