On the Concept of Model in Physics

The Educational Review, USA, 2023
The concept of model is the basis for theoretical and experimental research in physics. A model is defined as an application of physical theories to the description of a physical system. As a premise to the introduction of models, physical theories are defined as mathematical frameworks with a hypothetical-deductive structure, provided with a mapping ...

The Physics of the Vicsek model [PDF]

The European Physical Journal Special Topics, 2016
In these lecture notes, prepared for the Microswimmers Summer School 2015 at Forschungszentrum Juelich, I discuss the well known Vicsek model for collective motion and its main properties. In particular, I discuss its algorithmical implementation and the basic properties of its universality class. I present results from numerical simulations and insist

A New Approach for Approximate Solution of ADE: Physical-Based Modeling of Carriers in Doping Region

Mathematics, 2021
The electric behavior in semiconductor devices is the result of the electric carriers’ injection and evacuation in the low doping region, N-. The carrier’s dynamic is determined by the ambipolar diffusion equation (ADE), which involves the main physical ...
