dc.description.abstract | We study entanglement and discord in spin glass. By using the Edwards-Anderson XX model, we consider the Hamiltonian for three and four particles for nearest neighbor and next nearest neighbor interactions and to solve for the entanglement through concurrence. With a fixed mean and changing variances for the coupling J, the concurrence and discord are numerically plotted against the temperature. For J = 1, the critical temperature is found to be 2.106. The entanglement was found to increase beyond the critical temperature as the variance increases. The spin-spin correlation for three particles is plotted as a function of temperature T. © 2013 Astro Ltd. | |
