Dominos and the Gaussian free field

چکیده

We define a scaling limit of the height function on the domino tiling model (dimer model) on simplyconnected regions in Z and show that it is the “massless free field”, a Gaussian process with independent coefficients when expanded in the eigenbasis of the Laplacian. Résumé On définit une “limite d’échelle” pour la fonction d’hauteur dans le modèle des dimères dans Z. Nous montrons que la limite est un “champ libre gaussien”, un processus stochastique gaussien dont les coefficients, dans la base des fonctions propres du laplacien, sont indépendentes. AMS classification: primary 82B20, secondary 60G15 keywords: dimer model, domino tiling, Gaussian free field.

Numerical Investigation of the Non-Uniformity of the Electric Field Distribution by Injection of Net Electron Charge in TE CO2 Laser

In this report, the distribution and deviation of electric field in the active medium of the TE CO2 laser has been investigated due to the injection of net electron charge beam as a plasma generator. Some parameters of system have been considered, such as density and mean-free-path of injected charge beam. The electric potential and electric field distribution have been simulated by solving the...

Effects of intense laser pulse properties on wake field acceleration in magnetized plasma: Half-Sine Shape (HSS) and Gaussian Shape (GS) pulses

In this paper, we have simulated the excitation of wake fields in the interaction of an intensive laser pulses having Half-Sine and Gaussian time envelopes with a fully ionized cold plasma using particle in cell (PIC) method. We investigated the dependency of wake filed amplitude to different laser and plasma parameters such as laser wavelength, pulse duration and electron number density. In ad...

Theoretical Thermodynamic Study of Arginine and Lysine Amino Acids at different Solvents

The thermodynamic functions such as enthalpy, H°, Gibbs free energy, G°, and entropy, S°, of Arginine and Lysine amino acids were theoretically studied at different polar solvents by using ²Gaussian o3², software. First, the structural optimization of isolated Arginine and Lysine were done in the gas phase by applying the Density Functional Theory (B3LYP) level ...

Spatial Latent Gaussian Models: Application to House Prices Data in Tehran City

Latent Gaussian models are flexible models that are applied in several statistical applications. When posterior marginals or full conditional distributions in hierarchical Bayesian inference from these models are not available in closed form, Markov chain Monte Carlo methods are implemented. The component dependence of the latent field usually causes increase in computational time and divergenc...
