Effective action method for the Langevin equation.
In this paper we present a formulation of the nonlinear stochastic differential equation which allows for systematic approximations. The method is not restricted to the asymptotic, i.e., stationary, regime but can be applied to derive effective equations describing the relaxation of the system from arbitrary initial conditions. The basic idea is to reduce the nonlinear Langevin equation to an e...
متن کاملConformal Invariance of the D-Particle Effective Action
It is shown that the effective theory of D-particles has conformal symmetry with field-dependent parameters. This is a consequence of the supersymmetry. The string coupling constant is not transformed in contrast with the recent proposal of generalized conformal symmtery by Jevicki et al.[5][6] This conformal symmetry can also be generalized to other Dp-brane systems.

متن کاملInvestigating effective factors on the creation of organizational silence
Today, organizations are witnessing a destructive phenomenon called enterprise silence. The refusal of employees to provide their ideas and about organizational issues, ultimately leads to organizational degration and recession. This research intends to identify the factors that affect silence in organizations in order to come up with the best solutions to resolve this problem. This is an appli...
متن کاملParticle Creation in the Bell-Szekeres Spacetime
The quantization of a real massless scalar eld in a spacetime produced in a collision of two electromagnetic plane waves with constant wave fronts is considered. The background geometry in the interaction region, the Bell-Szekeres solution, is locally isometric to the conformally at Bertotti-Robinson universe lled with a uniform electric eld. It is shown that before the waves interact the Bogol...
متن کاملParticle production from non-local gravitational effective action
In this note we show, by using several examples, how the effective action for gravity obtained after integrating out matter fields, can be used to compute particle production rates and spectra for different space-time metrics. We also discuss the validity of this approach and compare it with other more conventional ones such as Bogolyubov transformations or the WBK method. Compared with the tra...
