A one - dimensional toy model of globular clusters
We introduce a one-dimensional toy model of globular clusters. The model is a version of the well-known gravitational sheets system, where we take additionally into account mass and energy loss by evaporation of stars at the boundaries. Numerical integration by the “exact” event-driven dynamics is performed, for initial uniform density and Gaussian random velocities. Two distinct quasi-stationa...
متن کاملThe Geometry of two dimensional Supersymmetric Nonlinear σ Model
In this report, we investigate the relation between supersymmetry (twisted and untwisted) and geometry for two dimensional σ model with target spaces of arbitrary signature, and Lorentzian or Euclidean world sheets. It can be shown that the number of allowed supersymmetry is constrained purely by the geometric considerations. The possible geometries are classified according to properties of the...
متن کاملToy model for a two-dimensional accretion disk dominated by Poynting flux
We discuss the effect of the Poynting flow on the magnetically dominated thin accretion disk, which is simplified to a two-dimensional disk on the equatorial plane. It is shown in the relativistic formulation that the Poynting flux by the rotating magnetic field with Keplerian angular velocity can balance the energy and angular momentum conservation of a steady accretion flow. PACS numbers: 97....
متن کاملTopology Change and the Emergence of Geometry in Two Dimensional Causal Quantum Gravity
In this thesis we analyze a very simple model of two dimensional quantum gravity based on causal dynamical triangulations (CDT). We present an exactly solvable model which indicates that it is possible to incorporate spatial topology changes in the nonperturbative path integral. It is shown that if the change in spatial topology is accompanied by a coupling constant it is possible to evaluate t...
متن کاملA two-dimensional numerical model of a planar solid oxide fuel cell
A two-dimensional CFD model of a planar solid oxide fuel cell (SOFC) has been developed.This model can predict the performance of SOFC at various operating and design conditions.The effect of Knudsen diffusion is accounted in the porous electrode (backing) and reaction zonelayers. The mathematical model solves conservation of electrons and ions and conservation ofspecies. The model is formulate...
