Title Proper : SPIN .hW CHARGE RESPONSE TO MAGNETIC FRIiSTR4TION HUBBAED MODEX
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : Unusual normal-state properties of strongly correlated electron materials have beendiscovered in recent years. They can not be evpIained by traditional theories. Muchwork has been devoted to expIoring the physical insight into these properties. In thedissertation, the study of spin and charge response to magnetic fixstration in theHubbard Mode1 is presented. Using exact diagonalization techniques, the eigenvd-ues and eigenvectors of a tw~dimensionaI Hubbard mode1 applied to a chster withperiodic boundary conditions have been obtained. Static and dynamic spin andcharge codation functions as wen as one-partide excitation spectra have been cal-dated. The effects of magnetic fitstration due to geometrical competition of differ-ent electron hopping terns are studied for various dopmg and short-range Coulombinteraction parameters. The calculated results are discussed in the framework ofmany-body physics-......-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
