Crossover Critical Behavior in the Three-Dimensional Ising Model
The character of critical behavior in physical systems depends on the range of interactions. In the limit of infinite range of the interactions, systems will exhibit mean-field critical behavior, i.e., critical behavior not affected by fluctuations of the order parameter. If the interaction range is finite, the critical behavior asymptotically close to the critical point is determined by fluctu...
متن کاملCritical behavior of the three - dimensional XY universality class
We improve the theoretical estimates of the critical exponents for the threedimensional XY universality class. We find α = −0.0146(8), γ = 1.3177(5), ν = 0.67155(27), η = 0.0380(4), β = 0.3485(2), and δ = 4.780(2). We observe a discrepancy with the most recent experimental estimate of α; this discrepancy calls for further theoretical and experimental investigations. Our results are obtained by ...
متن کاملthe effect of using critical discourse analytical tools on the improvement of the learners level of critical thinking in reading comprehension
?it is of utmost priority for an experienced teacher to train the mind of the students, and enable them to think critically and correctly. the most important question here is that how to develop such a crucial ability? this study examines a new way to the development of critical thinking utilizing critical discourse analytical tools. to attain this goal, two classes of senior english la...
D-XY Critical Behavior in Cuprate Superconductors
We outline the universal and finite temperature critical properties of the 3D-XY model, extended to anisotropic extreme type-II superconductors, as well as the universal quantum critical properties in 2D. On this basis we review: (i) the mounting evidence for 3D-XY behavior in optimally doped cuprate superconductors and the 3D to 2D crossover in the underdoped regime; (ii) the finite size limit...
متن کاملBreakdown of scaling in the nonequilibrium critical dynamics of the two-dimensional XY model
The approach to equilibrium, from a nonequilibrium initial state, in a system at its critical point is usually described by a scaling theory with a single growing length scale, xi(t) approximately t(1/z), where z is the dynamic exponent that governs the equilibrium dynamics. We show that, for the 2D XY model, the rate of approach to equilibrium depends on the initial condition. In particular, x...
