A note on the derivation of the Schrödinger-Langevin equation

  • Kunio Yasue


It is shown that the dynamics of open systems interacting with a chaotic environment can be formulated in a quantum mechanical scheme by means of Nelson's stochastic quantization procedures. As a result, a wave equation for a particle in the chaotic environment is found to be of the Schrödinger-Langevin type associated with an additional nonlinear and random potential.
