      ABSENCE OF FERROMAGNETISM IN ISING MODEL ON DIRECTED BARABASI-ALBERT NETWORK

      Shabat, Mohammed M.; Stauffer, D.; Sumour, M. A. (الجامعة الإسلامية - غزة, 2006)
      With up to 7 million spins, the existence of spontaneous magnetization of Ising spins on Directed Barabasi –Albert network is investigated by Monte Carlo simulations. We confirm our earlier result that the systems magnetization ...
    • Comparison of nonlinear with linear Barabási–Albert networks

      Sumour, Muneer A.; Lima, Fws; Shabat, Mohammed M.; Stauffer, D. (North-Holland, 2018)
      The nonlinear Barabási–Albert network (NLBA) of Krapivsky, Redner and Leyvraz (2000) is reinvestigated and modified here. We check the distribution of k (i) versus i for strong peaks and sharp gaps, where node number i has ...

      Test of universality in anisotropic 3D Ising model

      Sumour, Muneer A.; Stauffer, D.; Shabat, Mohammed M.; El-Astal, Ali H. (North-Holland, 2006)
      Chen and Dohm predicted theoretically in 2004 that the widely believed universality principle is violated in the Ising model on the simple cubic lattice with more than only six nearest neighbours. Schulte and Drope by Monte ...
