Existence of alpha-cluster Bose-Einstein condensation

Determine whether alpha-cluster Bose-Einstein condensation exists at the nucleon level.

Background

The paper identifies the possible existence of alpha-cluster Bose-Einstein condensation at the nucleon level as one of the unresolved fundamental questions motivating advances in high-precision nuclear measurements. This issue is distinct from the solid-liquid phase transition analyzed in the paper and is not resolved by its EQMD calculations.

References

The continuous advancement of high-precision measurement methods is driven by these unresolved fundamental questions, including the exploration and characterization of such exotic cluster configurations, the potential existence of $\alpha$-cluster Bose-Einstein condensation at the nucleon level, and the critical influence of cluster structures on the nuclear equation of state (EoS) in low-density astrophysical environments.
