Two Novel Approaches Based on the Thompson Theory and Shape Analysis for Determination of Equilibrium Structures of Nanoclusters: Cu8, Ag8 and Ag18 as study cases

Elkin Arias, Francisco Jose Caro-Lopera, Elizabeth Flórez, Jhon Fredy Pérez-Torres
2019 Journal of Physics, Conference Series  
For Cu8, Ag8 and Ag18 the shape analysis method provides more structures than the approach based on Thompson theory.  ...  A purely algebraic and geometrical approach based on shape analysis provides a consistent set for optimization of structures which converge to local and global low-energy configurations.  ...  The approach based on shape analysis only uses the algebraic and geometrical information and gives empirical group classifications which converges very fast to local and global low-energy structures, when  ...
