Feynman—Hibbs FH effective potentials constitute an appealing approach for investigations of many-body systems at thermal equilibrium since they allow us to easily include quantum corrections within standard classical simulations.
In particular, a new corrected expression for the FH4 effective potential is reported. FH2 and FH4 cluster energies and structures—obtained from energy optimization through a basin-hopping algorithm as well as classical Monte Carlo simulations—are reported and compared with reference path integral Monte Carlo calculations. However, the FH approach fails at lower temperatures, especially the quartic correction. It is thus crucial to assess the range of applicability of this formulation and, in particular, to apply the FH4 potentials with great caution.
A simple model of N isotropic harmonic oscillators allows us to propose a means of estimating the cutoff temperature for the validity of the method, which is found to increase with the number of atoms adsorbed on the coronene molecule.

Richard P. Feynman: The Scientist's Scientist One of the most famous scientists of the twentieth century, and an inexhaustible source of wonderful quotes, Richard Feynman shared the Nobel Prize in Physics with Julian Schwinger and Sin-Itiro Tomonaga for his contributions to the development of quantum electrodynamics. Hibbs first published Quantum Mechanics and Path Integrals, which Dover reprinted in a new edition comprehensively emended by Daniel F. Styer in In the Author's Own Words:. If you want to learn about nature, to appreciate nature, it is necessary to understand the language that she speaks in. Quantum Mechanics and Path Integrals.
