Gaussian Quantum Fluctuations in Interacting Many Particle Systems

  • Michael Hartmann
  • Günter mahler
  • Ortwin Hess


We consider a many particle quantum system, in which each particle interacts only with its nearest neighbours. Provided that the energy per particle has an upper bound, we show, that the energy distribution of almost every product state becomes a Gaussian normal distribution in the limit of infinite number of particles. We indicate some possible applications.
