The Langevin Equation

2020
As a prelude, some of the important properties of the Maxwellian distribution of velocities in thermal equilibrium are highlighted. The basic equation of motion of a particle in a fluid incorporating the effects of random molecular collisions, the Langevin equation, is introduced.

The Langevin Equation

2014
In this chapter, we study the Langevin equation and the associated Fokker –Planck equation. In Sect. 6.1, we introduce the equation and study some of the main properties of the corresponding Fokker–Planck equation. In Sect. 6.2 we give an elementary introduction to the theories of hypoellipticity and hypocoercivity. In Sect.

The Langevin Equation

1997
The generalized Langevin equation describes processes in a mechanical system with both deterministic and random forces which have comparable magnitudes (i.e., neither the deterministic nor random part can be neglected) and the random force is a transformed white noise. Examples of such processes are well known in physics.

Generalized Langevin Equations

2012
Diese Arbeit ist wie folgt aufgebaut: Das erste Kapitel stellt verallgemeinerte Langevingleichungen als eine Familie von stochastischen Differential-Integralgleichungen vor, die mittels des Zwanzigschen Projektionsformalismus gewonnen werden. Ausgangspunkt ist ein statistisch-mechanisches Modell, das die Wechselwirkung eines makroskopischen Systems mit
