Schwinger-boson mean-field theory for S
in the study of one-dimensional spin chains with nearestneighbor antiferromagnetic exchange interaction J, following the conjecture by Haldane' that integer spin chains have a singlet ground state with a finite gap EH in the excitation spectrum, whereas the excitation spectrum for half-integer spins is gapless. More recently, the physics of S =1 open spin chains has received new attention stimu...
متن کاملthe 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 ...
15 صفحه اولMean Field Studies of the 2 D Kondo Lattice Model
We develop and study a model of the Kondo lattice system under the mean field approximation using a HartreeFock procedure as the spin polarization of the system is varied. The goal of this investigation is to provide a realistic model and a starting point for further investigations using more sophisticated techniques, as well as to provide information on mean field solutions calculated on large...
متن کاملThe Ferromagnetic Kondo Model for Manganites: Phase Diagram and Charge Segregation Effects
The phase diagram of the ferromagnetic Kondo model for manganites is investigated using computational techniques. In clusters of dimensions 1 and 2, Monte Carlo simulations in the limit where the localized spins are classical show a rich low temperature phase diagram with three dominant regions: (i) a ferromagnetic phase, (ii) phase separation between hole-poor antiferromagnetic and hole-rich f...
متن کاملIncommensurate phase of a triangular frustrated Heisenberg model studied via Schwinger-boson mean-field theory.
We study a triangular frustrated antiferromagnetic Heisenberg model with nearest-neighbor interactions J(1) and third-nearest-neighbor interactions J(3) by means of Schwinger-boson mean-field theory. By setting an antiferromagnetic J(3) and varying J(1) from positive to negative values, we disclose the low-temperature features of its interesting incommensurate phase. The gapless dispersion of q...
