The Kac Jordan superalgebra: automorphisms and maximal subalgebras
Alberto Elduque, Jesus Laliena, Sara Sacristan
The group of automorphisms of the Kac Jordan superalgebra is described, and used to classify the maximal subalgebras.
Magnetic dipolar ordering and relaxation in the high-spin molecular cluster compound Mn6
A. Morello, F. L. Mettes, O. N. Bakharev +5
Few examples of magnetic systems displaying a transition to pure dipolar magnetic order are known to date, and single-molecule magnets can provide an interesting example. The molec…
Lie algebras with S4-action and structurable algebras
Alberto Elduque, Susumu Okubo
The normal symmetric triality algebras (STA's) and the normal Lie related triple algebras (LRTA's) have been recently introduced by the second author, in connection with the princi…
Time relaxation of interacting single--molecule magnets
J. F. Fernandez, J. J. Alonso
We study the relaxation of interacting single--molecule magnets (SMMs) in both spatially ordered and disordered systems. The tunneling window is assumed to be, as in Fe8, much narr…
Immunization of Real Complex Communication Networks
Jesus Gomez-Gardenes, Pablo Echenique, Yamir Moreno
Most communication networks are complex. In this paper, we address one of the fundamental problems we are facing nowadays, namely, how we can efficiently protect these networks. To…
Giant isotope effect in the incoherent tunneling specific heat of the molecular nanomagnet Fe8
M. Evangelisti, F. Luis, F. L. Mettes +2
Time-dependent specific heat experiments on the molecular nanomagnet Fe8 and the isotopic enriched analogue 57Fe8 are presented. The inclusion of the 57Fe nuclear spins leads to a…
