We consider RVB state as a variational estimate for the ground state of Heisenberg antiferromagnet in square lattice. We present numerical calculation of energy, spin-spin correlation function and spin excitation spectrum. We show, that the quantum flactuations reduce of magnetization respect to Neel order. Our results are in good agreement with other methods such as spin-wave calculation a...
We derive via the interaction "representation" the many-body wave function for harmonically confined electrons in the presence of a magnetostatic field and perturbed by a spatially homogeneous time-dependent electric field-the Generalized Kohn Theorem (GKT) wave function. In the absence of the harmonic confinement - the uniform electron gas - the GKT wave function reduces to the Kohn Theorem wa...
The study of surface waves in a layered media has their viable application in geophysical prospecting. This paper presents an analytical study on the dispersion of torsional surface wave in a pre-stressed heterogeneous layer sandwiched between a pre-stressed anisotropic porous semi-infinite medium and gravitating anisotropic porous half-space. The non-homogeneity within the intermediate layer a...
shear-wave velocity ( ) is an important parameter used for site characterization in geotechnical engineering. however, dispersion curve inversion is challenging for most inversion methods due to its high non-linearity and mix-determined trait. in order to overcome these problems, in this study, a joint inversion strategy is proposed based on the particle swarm optimization (pso) algorithm. the ...
در این پایان نامه سعی کرده ایم برای یک سری از ساختارهای خطوط انتقالی که عموما با روش های عددی یا با استفاده از نرم افزارهای full wave حل می شوند، مدلی ساده و در عین حال دقیق ارایه دهیم که می تواند رفتار مدل فیزیکی را از دید پایانه ها به خوبی پیش بینی کند. این ساختار خطوط انتقال میکرواستریپی می شوندکه در بردهای pcb چند لایه به صورت عمود بر هم قرار می گیرند. خطوط مایکرواستریپ عمود برهم به دلیل ...
In this paper, we show how nonstandard consequence operators, ultralogics, can generate the general informational content displayed by probability models. In particular, a model that states a specific probability that an event will occur and those models that use a specific distribution to predict that an event will occur. These results have many diverse applications and even apply to the colla...

The quantum wave function of multiple particles provides additional information which is inaccessible to detectors working alone. Here, we introduce the coincidence wavefront sensing (CWS) method reconstruct phase multiphoton transverse spatial function. spatially resolved photon counting involved. Numerical simulations two-photon cases using weak measurement sensor are performed test its corre...
