An equation-free approach to coarse-graining the dynamics of networks
equation-free approach coarse-graining dynamics of networks
2012/2/29
We propose and illustrate an approach to coarse-graining the dynamics of evolving networks (networks whose connectivity changes dynamically). The approach is based on the equation-free framework: shor...
Extension of the Finite Integration Technique including dynamic mesh refinement and its application to self-consistent beam dynamics simulations
Finite Integration Technique, Adaptive Dynamic Mesh Refinement, Particle-In-Cell
2011/9/6
An extension of the framework of the Finite Integration Technique (FIT) including dynamic and adaptive mesh refinement is presented. After recalling the standard formulation of the FIT, the proposed m...
Driven Langevin dynamics: heat, work and pseudo-work
Driven Langevin dynamics heat pseudo-work Statistical Mechanics
2011/8/17
Abstract: Common algorithms for simulating Langevin dynamics are neither statistically time-reversible, nor do they preserve the equilibrium distribution. Instead, even with a time-independent Hamilto...
Molecular dynamics simulation of the recrystallization of amorphous Si layers: Comprehensive study of the dependence of the recrystallization velocity on the interatomic potential
Molecular dynamics simulation amorphous Si layers the recrystallization velocity
2011/8/3
Abstract: The molecular dynamics method is applied to simulate the recrystallization of an amorphous/crystalline silicon interface. The atomic structure of the amorphous material is constructed with t...
Solid phase epitaxy amorphous silicon re-growth: some insight from empirical molecular dynamics simulation
Nucleation and growth Theory and models of film growth
2011/9/1
The modelling of interface migration and the associated diffusion mechanisms at the nanoscale level is a challenging issue. For many technological applications ranging from nanoelectronic devices to s...

2011/8/30
Mathematical models and computer algorithms are developed to calculate dynamic stress concentration and fracture wave propagation in a reinforced composite sheet. The composite consists of a regular s...
Numerical Feynman integrals for density operator dynamics using more than one mesh: faster convergence and significant reduction of computational cost
Feynman integral path integral QUAPI Feynman-Vernon
2010/10/26
The Feynman integral is one of the most accurate methods for calculating density operator dy-
namics in open quantum systems. However, the number of time steps that can realistically be used is alway...
Spin systems dynamics and faults detection in threshold networks
Spin systems dynamics faults detection threshold networks
2010/10/20
We consider an agent on a fixed but arbitrary node of a known threshold network, with the
task of detecting an unknown missing link/node. We obtain analytic formulas for the probability of success, w...
A unified theory of chaos linking nonlinear dynamics and statistical physics
chaos linking nonlinear dynamics statistical physics
2010/4/21
A fundamental issue in nonlinear dynamics and statistical physics is how to distinguish chaotic from stochastic fluctuations in short experimental recordings. This dilemma underlies many complex syste...
q-entropies and the entanglement dynamics of two-qubits interacting with an environment
q-Entropies Entanglement dynamics
2010/7/5
We investigate entropic aspects of the quantum entanglement dynamics of two-qubits systems interacting with an environment. In particular we consider the detection, based on the violation of classical...
