Cluster Analysis for Percolation on Two Dimensional Fully Frustrated System
The percolation of Kandel, Ben-Av and Domany clusters for 2d fully frustrated Ising model is extensively studied through numerical simulations. Critical exponents, cluster distribution and fractal dimension of percolative cluster are given.
متن کاملIncremental Configuration Space Construction for Mechanism Analysis
Abstract We present an incremental configuration space (CS) construction algorithm for mechanisms described as collections of subassemblies of rigid parts . The inputs are the initial subassembly configurations and the subassembly CSs partitioned into uniform motion regions in which part contacts are constant and motions are monotonic . The output is a partition of the mechanism CS into uniform...
متن کاملThermal Excitations of Frustrated Xy Spins in Two Dimensions
We present a new variational approach to the study of phase transitions in frustrated 2D XY models. In the spirit of Villain’s approach for the ferromagnetic case we divide thermal excitations into a low temperature long wavelength part (LW) and a high temperature short wavelength part (SW). In the present work we mainly deal with LW excitations and we explicitly consider the cases of the fully...
متن کاملEntropy-vanishing transition and glassy dynamics in frustrated spins.
In an effort to understand the glass transition, the dynamics of a nonrandomly frustrated spin model has been analyzed. The phenomenology of the spin model is similar to that of a supercooled liquid undergoing the glass transition. The slow dynamics can be associated with the presence of extended stringlike structures which demarcate regions of fast spin flips. An entropy-vanishing transition, ...
متن کاملMacroscopic signature of protected spins in a dense frustrated magnet.
The inability of systems of interacting objects to satisfy all constraints simultaneously leads to frustration. A particularly important consequence of frustration is the ability to access certain protected parts of a system without disturbing the others. For magnets such "protectorates" have been inferred from theory and from neutron scattering, but their practical consequences have been uncle...
