Discrete models of dislocations and their motion in cubic crystals
A. Carpio, L. L. Bonilla
A discrete model describing defects in crystal lattices and having the standard linear anisotropic elasticity as its continuum limit is proposed. The main ingredients entering the…
Cellularization of classifying spaces and fusion properties of finite groups
R. J. Flores, J. Scherer
One way to understand the mod p homotopy theory of classifying spaces of finite groups is to compute their BZ/p-cellularization. In the easiest cases this is a classifying space of…
Theory of charge fluctuations and domain relocation times in semiconductor superlattices
L. L. Bonilla
Shot noise affects differently the nonlinear electron transport in semiconductor superlattices depending on the strength of the coupling among the superlattice quantum wells. Stron…
Postnikov pieces and BZ/p-homotopy theory
Natalia Castellana, Juan A. Crespo, Jerome Scherer
We present a constructive method to compute the cellularization with respect to K(Z/p, m) for any integer m > 0 of a large class of H-spaces, namely all those which have a finite n…
Many body effects on - axis properties: out of plane coherence and bilayer splitting
F. Guinea, M. P. Lopez-Sancho, M. A. H. Vozmediano
The out-of-plane hopping in layered metals with strong electronic correlation is analyzed theoretically. By studying the effects of in-plane interactions on the interlayer tunnelli…
Deconstructing Hopf spaces
Natalia Castellana, Juan A. Crespo, Jerome Scherer
We characterize Hopf spaces with finitely generated cohomology as an algebra over the Steenrod algebra. We "deconstruct" the original space into an H-space Y with finite mod p coho…
