Finite-size effects on current correlation functions.
We study why the calculation of current correlation functions (CCFs) still suffers from finite-size effects even when the periodic boundary condition is taken. Two important one-dimensional, momentum-conserving systems are investigated as examples. Intriguingly, it is found that the state of a system recurs in the sense of microcanonical ensemble average, and such recurrence may result in oscil...
متن کاملFinite-Size Correlation Length and Violations of Finite-Size Scaling
We address the problem of the definition of the finite-volume correlation length. First, we study the large-N limit of the N -vector model, and we show the existence of several constraints on the definition if regularity of the finite-size scaling functions and correct anomalous behaviour above the upper critical dimension are required. Then, we study in detail a model in which the zero mode in...
متن کاملLine tension at wetting: finite-size effects and scaling functions
We study trie effect of limite system size on trie tension r of a three-phase contact fine. This is especially important in systems with forces that are sufliciently long-ranged for r to diverge in trie thermodynamic Iimit. Near wetting phase transitions we propose an anisotropic finite-size scaling hypothesis, which takes into account trie elfect of thermal capillary-wave fluctuations. Trie si...
متن کاملUniversal Finite-size-scaling Functions
The idea of universal finite-size-scaling functions of the Ising model is tested by Monte Carlo simulations for various lattices. Not only regular lattices such as the square lattice but quasiperiodic lattices such as the Penrose lattice are treated. We show that the finite-size-scaling functions of the order parameter for various lattices are collapsed on a single curve by choosing two nonuniv...
متن کاملFinite Temperature Correlation Functions in Integrable QFT
Finite temperature correlation functions in integrable quantum field theories are formulated only in terms of the usual, temperature-independent form factors, and certain thermodynamic filling fractions which are determined from the thermodynamic Bethe ansatz. Explicit expressions are given for the one and two-point functions. Typeset using REVTEX 1
