# Universality of density of states in configuration space

## TL;DR

This paper demonstrates that the density of microscopic states is universal across different lattice systems, enabling efficient prediction of configurations, free energy, and phase diagrams using minimal first-principles calculations.

## Contribution

It establishes the universality of density of states in non-interacting systems, simplifying computational approaches for material properties.

## Key findings

- Density of states is universal in non-interacting lattice systems.
- Statistical interdependence vanishes across different lattices.
- Configuration and phase information can be obtained with minimal calculations.

## Abstract

In this study, we confirm the universality of density of microscopic states in non-interacting system; this means statistical interdependence is vanished in any lattices. This enable one to obtain information of configuration of solute atoms, free energy, phase diagram with performing first-principles calculation on few special microscopic states combined with our established theory.
