OpenAI reports positive-temperature condensation for dilute hard spheres
- Mathematics
- Theoretical Physics
For each hard-sphere radius a>0 and every sufficiently small fixed density ρ>0, there is a temperature T(a,ρ)>0 independent of volume at which the exact three-dimensional canonical Gibbs state has a positive condensate fraction in the constant orbital as N/L³ tends to ρ.
