چکیده

Aharonov and Reznik have recently argued that the form of the probabilistic predictions of quantum theory can be seen to follow from properties of macroscopic systems. An error in their argument is identified .

How macroscopic properties dictate microscopic probabilities

Given that quantum theory is probabilistic, is there a fundamental physical principle that dictates the form of the quantum probability law? We will argue that, indeed, the assigned probabilities for a given test performed on a large sample of identical systems are dictated by the classical-like properties of macroscopic systems. Consider a sample of N identically prepared nonentangled spins in...

Cellular Automata Simulation of a Bistable Reaction-Diffusion System: Microscopic and Macroscopic Approaches

The Cellular Automata method has been used to simulate the pattern formation of the Schlögl model as a bistable Reaction-Diffusion System. Both microscopic and macroscopic Cellular Automata approaches have been considered and two different methods for obtaining the probabilities in the microscopic approach have been mentioned. The results show the tendency of the system towards the more sta...

A “v2-f Based” Macroscopic K-Ε Model for Turbulent Flow through Porous Media

In this paper a new macroscopic k-ε model is developed and validated for turbulent flow through porous media for a wide range of porosities. The morphology of porous media is simulated by a periodic array of square cylinders. In the first step, calculations based on microscopic v2 − f model are conducted using a Galerkin/Least-Squares finite element formulation, employing equalorder bilinear ve...

Systems with two symmetric absorbing states: relating the microscopic dynamics with the macroscopic behavior.

We propose a general approach to study spin models with two symmetric absorbing states. Starting from the microscopic dynamics on a square lattice, we derive a Langevin equation for the time evolution of the magnetization field, that successfully explains coarsening properties of a wide range of nonlinear voter models and systems with intermediate states. We find that the macroscopic behavior o...

Fluctuations of energy injection rate in a shear flow

We study the instantaneous and local energy injection in a turbulent shear flow driven by volume forces. The energy injection can be both positive and negative. Extremal events are related to coherent streaks. The probability distribution is asymmetric, deviates slightly from a Gaussian shape and depends on the position in shear direction. The probabilities for positive and negative injection a...
