Local moment formation in quantum point contacts.

Spin-density-functional theory of quantum point contacts (QPCs) reveals the formation of a local moment with a net of one electron spin in the vicinity of the point contact-supporting the recent report of a Kondo effect in a QPC. The hybridization of the local moment to the leads decreases as the QPC becomes longer, while the on site Coulomb-interaction energy remains almost constant.

A Model of Void Formation

We introduce a simple model for the formation of voids. In this model the underdensity of galaxies in voids is the product of two factors. The first arises from a gravitational expansion of the negative density perturbation. The second is due to biasing: galaxies are less likely to form in an underdense region. One feature of the model is an upper cutoff in void sizes. We calculate the volume f...

Void formation at the interface in Sn/Cu solder joints

The effect of electroplated Cu (EPC), electroplated Sn (EPS) and Cu addition (0.7 wt.%) on the void formation at the reaction interfacewas investigated through the reaction of solderswithCu substrates. The voidswere observed at the Cu3Sn/EPC interface in the Sn/EPC joints after aging at 150 C, while not at the Cu3Sn/high purity Cu (HPC) interface in the Sn/HPC joints even after aging at 180 C f...

Formation of the Supercluster-Void Network

A review of the study of superclusters based on the 2dFGRS and SDSS is given. Real superclusters are compared with models using simulated galaxies of the Millennium Run. We show that the fraction of very luminous superclusters in real samples is about five times greater than in simulated samples. Superclusters are generated by large-scale density perturbations which evolve very slowly. The abse...

A Local Void and the Accelerating Universe

Corresponding to the recent observational claims that we are in a local void (an underdense region) on scales of 200 − 300 Mpc, the magnitude-redshift relation in a cosmological model with a local void is investigated. It is already evident that the accelerating behavior of high-z supernovae can be explained in this model, because the local void plays a role similar to the positive cosmological...
