| Abstract: | We show with simple arguments that, as a consequence of the Poisson equation, the correlations of a charged system at equilibrium decay faster than any inverse power, if they are integrable and monotonous at infinity. For all other longrange systems (with potential (x) b¦x¦–s, ¦x¦   , 0v,s } 2), the decay is bounded below by an inverse power.Partially supported by the Swiss National Foundation for Scientific Research. |
