Self-consistent generalized Langevin equation theory for liquids of non-spherical brownian particles
(2015-01)
"A theoretical approach is proposed in order to describe, in the absence of hydrodynamic interactions, the equilibrium self and collective dynamics of brownian liquids conformed by non-spherical interacting particles.

Role of noise in population dynamics cycles
(AMER PHYSICAL SOC, 2009)
Noise is an intrinsic feature of population dynamics and plays a crucial role in oscillations called phase-forgetting quasicycles by converting damped into sustained oscillations. This function of noise becomes evident ...
Numerical integration of the stochastic Landau-Lifshitz-Gilbert equation in generic time-discretization schemes
(American Physical Society, 2014-08)
We introduce a numerical method to integrate the stochastic Landau-Lifshitz-Gilbert equation in spherical coordinates for generic discretization schemes. This method conserves the magnetization modulus and ensures the ...
Memory effects in the asymptotic diffusive behavior of a classical oscillator described by a generalized Langevin equation
(American Physical Society, 2008-03)
We investigate the memory effects present in the asymptotic dynamics of a classical harmonic oscillator governed by a generalized Langevin equation. Using Laplace analysis together with Tauberian theorems we derive asymptotic ...
Models for microtubule cargo transport coupling the Langevin equation to stochastic stepping motor dynamics: Caring about fluctuations
(American Physical Society, 2016-01)
One-dimensional models coupling a Langevin equation for the cargo position to stochastic stepping dynamics for the motors constitute a relevant framework for analyzing multiple-motor microtubule transport. In this work we ...
Dynamical analysis of bidimensional coulomb fluids on a disc using the langevin equation
(Universidad de los AndesFísicaFacultad de CienciasDepartamento de Física, 2019)
Este proyecto presenta un análisis dinámico de una conjuración compuesta de un disco y partículas cargadas. Usando la ecuación de Langevin miramos el comportamiento del modelo antes del equilibrio y durante el equilibrio. ...
Interfacial Dynamics and its relations with "negative" surface viscosities measured at water-air interfaces covered with a cationic surfactant
(American Chemical Society, 2019-06)
We studied the dynamics of a cationic surfactant monolayer, Gemini 12-2-12, at the air-water interface for surfactant aqueous solutions at concentrations below the critical micelle concentration. We present surface rheology ...
NOISE and ULTRAVIOLET DIVERGENCES IN SIMULATIONS of GINZBURG-LANDAU-LANGEVIN TYPE of EQUATIONS

NOISE and ULTRAVIOLET DIVERGENCES IN SIMULATIONS of GINZBURG-LANDAU-LANGEVIN TYPE of EQUATIONS
(World Scientific Publ Co Pte Ltd, 2012-08-01)
The time evolution of an order parameter towards equilibrium can be described by nonlinear Ginzburg-Landau (GL) type of equations, also known as time-dependent nonlinear Schrodinger equations. Environmental effects of ...
