No free lunch for effective potentials: general comment for Faraday FD144

Soft Condensed Matter 2010-01-08 v2

Abstract

I briefly review the problem of representability -- a single coarse-grained effective pair potential cannot simultaneously represent all the properties of an underlying more complex system -- as well as a few other subtleties that can arise in interpreting coarse-grained potentials.
