Self-consistent Born approximation for the hole motion in the three-band model: A comparison with photoemission experiments.
The dispersion relation of the single hole in CuO2 plane is calculated in the self-consistent Born approximation for the thee-band Hamiltonian. We find that direct oxygen-oxygen hopping removes the strong anisotropy of the hole spectrum around the band minima. Our results compare well with recent photoemission measurements of single hole dispersion relation in the Sr2CuO2Cl2. PACS: 71.25.-s, 71...
متن کاملthe 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...
15 صفحه اولA Self-Consistent Technique for the Construction and Evaluation of the Three-Parameter Corresponding States Principles
A self-consistent approach for the evaluation of the existing three-parameter corresponding states principles of non-polar fluids and the calculation of the corresponding states parameters is presented. This self consistent approach is based upon the assumption that the contribution of the third parameter to the thermophysical properties is much smaller than the contributions of the first two p...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
the use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
