## Abstract

Combining the recent Piskulich-Thompson approach [Z. A. Piskulich and W. H. Thompson, J. Chem. Phys.

152, 011102 (2020)] with isomorph theory, from a single simulation the structure of a single-component

Lennard-Jones (LJ) system is obtained at an arbitrary state point in almost the whole liquid region of the

temperature-density phase diagram. The LJ system exhibits two temperature ranges where the van’t Hoff

assumption that energetic and entropic forces are temperature independent is valid to a good approximation.

A method to evaluate the structure at an arbitrary state point along an isochore from the knowledge of structures

at two temperatures on the isochore is also discussed. We argue that, in general, the structure of any hidden

scale-invariant system obeying the van’t Hoff assumption in the whole range of temperatures can be determined

in the whole liquid region of the phase diagram from a single simulation.
