A potential energy surface is generally used within the adiabatic or
Born-Oppenheimer approximation in quantum mechanics and statistical
mechanics to model chemical reactions and interactions in simple chemical
and physical systems. The name comes from the fact that the total energy
of an atom arrangement can be represented as a curve or multidimensional
surface, with atomic positions as variables. The best visualization for a
layman would be to think of a landscape, where going North-South and East-
West are two independent variables, and the height of the land we are on
would be the energy associated with a given value of such variables.
There is a natural correspondence between potential energy surfaces as
they exist and their application in potential theory, which associates
and studies harmonic functions in relation to these surfaces.
