Effective field theory of the zero-temperature triangular-lattice antiferromagnet: A monte carlo study
Using a Monte Carlo coarse-graining technique introduced by Binder [Z. Phys. B 43, 119 (1981)], we have explicitly constructed the continuum field theory for the zero-temperature triangular Ising antiferromagnet. We verify the conjecture that this is a Gaussian theory of the height variable in the interface representation of the spin model. We also measure the height-height correlation function...
متن کاملThermal Buckling Analysis of Graphene Nanoplates Based on the Modified Couple Stress Theory using Finite Strip Method and Two-Variable Refined Plate Theory
Graphene is one of the nanostructured materials that has recently attracted the attention of many researchers. This is due to the increasing expansion of nanotechnology and the application of this nanostructure in technology and industry owing to its mechanical, electrical and thermal properties. Thermal buckling behavior of single-layered graphene sheets is studied in this paper. Given the fai...
متن کاملThermal Vibration of Composites and Sandwich Laminates Using Refined Higher Order Zigzag Theory
Vibration of laminated composite and sandwich plate under thermal loading is studied in this paper. A refined higher order theory has been used for the purpose. In order to avoid stress oscillations observed in the implementation of a displacement based finite element, the stress field derived from temperature (initial strains) have been made consistent with total strain field. So far no study ...
متن کاملRotating magneto-thermoelastic rod with finite length due to moving heat sources via Eringen’s nonlocal model
The article is concerned with a new nonlocal model based on Eringen’s nonlocal elasticity and generalized thermoelasticity. A study is made of the magneto-thermoelastic waves in an isotropic conducting thermoelastic finite rod subjected to moving heat sources permeated by a primary uniform magnetic field and rotating with a uniform angular velocity. The Laplace transform technique with respect ...

This manuscript is the collection of lectures given in the summer school on strongly correlated electron systems held at Isfahan university of technology, June 2007. A short overview on quantum magnetism and spin systems is presented. The numerical exact diagonalization (Lanczos) alghorithm is explained in a pedagogical ground. This is a method to get some ground state properties on finite clus...
