Alpha-particle (quartet) condensation in homogeneous spin-isospin symmetric nuclear matter is investigated. The usual Thouless criterion for the critical temperature is extended to the quartet case. The in-medium four-body problem is strongly simplified by the use of a momentum projected mean field ansatz for the quartet. The self-consistent single particle wave functions are shown and discussed for various values of the density at the critical temperature.

Initial spin fluctuations as a probe of cluster spin structure in $^{16}\mathrm{O}$ and $^{20}\mathrm{Ne}$ nuclei
nucl-th 2025-12 unverdicted novelty 7.0

Alpha clustering in 16O and 20Ne suppresses initial spin fluctuations in relativistic collisions, with a scaled ratio of fluctuations between the two systems proposed as a probe of cluster geometry.
