Tunnelling states in a potential of hexagonal symmetry

The tunnel splitting of the ground state multiplet in a potential of the form V 0 cos 6 φ is calculated both in the weak perturbation and in the high barrier limit. In the latter limit a true variational calculation is performed and this gives better results than obtained by previous methods. On a c...

Description
Summary:The tunnel splitting of the ground state multiplet in a potential of the form V 0 cos 6 φ is calculated both in the weak perturbation and in the high barrier limit. In the latter limit a true variational calculation is performed and this gives better results than obtained by previous methods. On a calculé le fendage tunnel de la multiplet état fondamentale dans un potentiel de la forme V 0 cos 6 φ en perturbation faible et en heute limite barrière. Dans la dernière limite, on a fait un vrai variational calcul qui donne meilleurs résultats par rapport les methodes antèrieures.
