Fragmentation Temperature of 1D and 3D Quantum Droplets in a BEC Mixture
Quantum droplets in BEC mixtures fragment to lower free energy, with 3D droplets splitting under strong interspecies interactions near the minimum atom number and 1D droplets fragmenting unless interactions are similar and density high, expelling atoms at higher temperatures while leaving persistent
