Size-induced melting and reentrant freezing in fullerene-doped helium clusters
The structural and dynamical stabilities of (ProQuest: Formulae and/or non-USASCII text omitted) He sub(N) clusters are theoretically investigated using global optimization and path-integral simulation methods. Up to N = 32, the fullerene ion traps the helium atoms onto sixfold and fivefold faces, s...

| description | The structural and dynamical stabilities of (ProQuest: Formulae and/or non-USASCII text omitted) He sub(N) clusters are theoretically investigated using global optimization and path-integral simulation methods. Up to N = 32, the fullerene ion traps the helium atoms onto sixfold and fivefold faces, strongly enough to negate vibrational delocalization. Above this size, geometric frustration takes over and the clusters grow as a thin but homogeneous liquid layer. However, as their size reaches 60 atoms, corrugation barriers are suppressed and the cluster is again rigidlike. Additional fluid layers are predicted to arise above 72 atoms. |
