Selective Migration of Cd in Amorphous Cd–Sb Films

Abstract

If the AdS/CFT correspondence is valid in the Coulomb branch, the potential between waves on a pair of test branes in the bulk should be reproduced by the relevant Yang-Mills theory effective action on the boundary. Earlier work has provided evidence for this in the case of constant gauge field brane waves. In this paper we provide concrete evidence for an earlier proposal that the effects of exchange of supergravity modes with nonzero momentum in the brane directions are encoded in certain terms involving derivatives of the field strength in the gauge theory effective action. We explicitly calculate the force quadratic in the field strengths coming from the exchange of nonzero momentum two form fields between two 3-branes in AdS 5 × S 5 to lowest nontrivial order in the momentum. We show that this is exactly the same as that between the branes living in flat space. The result is in agreement with the gauge theory effective action and consistent with the non-renormalization property of this term. We comment on the relationship of other "acceleration" terms in the SYM effective action with quantities in supergravity.

“…Это затрудняет получение пленок и слоев этих соединений методом испарения в вакууме. Пленки получаются обогащенными летучим компонентом Cd или Zn, отличаются по составу от исходных стехиометрических соединений CdSb и ZnSb [3,4]. Поэтому использование невакуумных методов, например метода жидкофазной эпитаксии [5], дает возможность получать более однородные по составу эпитаксиальные слои.…”
