This paper proposes a formal definition of the notion of technological paradigm. This definition is consistent with the fundamental proposition of Kuhnian philosophy of science, that progress only happens through successive and abrupt shifts of paradigm. It also helps clarifying a number of...

Monte Carlo (MC) simulations, finite-size scaling and theoretical analysis have been carried out to study the critical behavior of long linear particles of length k (k-mers) on honeycomb lattices. A nematic phase, characterized by a big domain of parallel k-mers, is separated from the isotropic...

The influence of random site dilution on the critical properties of the two-dimensional Ising model on a square lattice was explored by Monte Carlo simulations with the Wang–Landau sampling. The lattice linear size was L=20–120 and the concentration of diluted sites q=0.1,0.2,0.3. Its pure...

We restudy the phase diagram of the 2D-Ising model with competing interactions J<Subscript>1</Subscript> on nearest neighbour and J<Subscript>2</Subscript> on next-nearest neighbour bonds via Monte-Carlo simulations. We present the finite temperature phase diagram and introduce computational methods which allow us to calculate transition...</subscript></subscript>

In this work we report Monte Carlo simulations of a 2D Ising model, in which the statistics of the Metropolis algorithm is replaced by the nonextensive one. We compute the magnetization and show that phase transitions are present for q ≠ 1. A q - phase diagram (critical temperature vs. the...
