S ep 2 00 5 Application of large deviation theory to the mean - field φ 4 - model
A large deviation technique is used to calculate the microcanonical entropy function s(v,m) of the mean-field φ4-model as a function of the potential energy v and the magnetization m. As in the canonical ensemble, a continuous phase transition is found. An analytical expression is obtained for the critical energy vc(J) as a function of the coupling parameter J .
متن کاملApplication of Mean Field Games to Growth Theory
This article discusses the interaction between economic growth in the sense of human capital accumulation and the dynamics of inequalities. We use a mean-field game framework in which individuals improve their human capital both to improve their wages and to avoid potential competition with less skilled individuals. Our contribution is twofold. First, we exhibit a mechanism in which competition...
متن کاملDynamical mean-field theory of noisy spiking neuron ensembles: application to the Hodgkin-Huxley model.
A dynamical mean-field approximation (DMA) previously proposed by the present author [H. Hasegawa, Phys. Rev E 67, 041903 (2003)] has been extended to ensembles described by a general noisy spiking neuron model. Ensembles of N-unit neurons, each of which is expressed by coupled K-dimensional differential equations (DEs), are assumed to be subject to spatially correlated white noises. The origin...
متن کاملLarge Deviation Theory
If we draw a random variable n times from Q, the probability distribution of the sum of the random variables is given by Q. This is the convolution of Q with itself n times. As n → ∞, Q tends to a normal distribution by the central limit theorem. This is shown in Figure 1. The top line is a computed normal distribution with the same mean as Q. However, as shown in Figure 3, when plotted on a lo...
متن کاملLarge deviation theory and applications Application I: The parabolic Anderson model
The solution u is influenced by the competition between the Laplacian ∆ which has a smoothing effect, and the random potential, which makes the solution spatially irregular. In general, it is believed that there is a small number of relevant island where the potential takes especially large values, which are important for the large times asymptotics of the solution. This effect is called interm...
