QUANTUM DECOHERENCE



Decoherence is the irreversible formation of quantum correlations of a system with its environment. These correlations lead to entirely new properties and behavior compared to that shown by isolated objects. It is the destruction of quantum coherence between preferred states associated with the observables monitored by the environment.

CLACSA XIII

CLACSA XIII is the continuation of a series of events that started in 1980 as the Latin American Symposium on Surface Physics. Due to the increasingly interdisciplinary nature of this field and its applications, the name of the series was changed into Latin American Conference on Surface Science and Applications. CLACSA XIII will be held in Santa Marta Colombia during the week of 3-7 December 2007.This conference is the thirteen edition of a successful series that is realized every two years. This conference aims to bring together physicists, chemists, biologists and engineers interested in new materials and Nanotechnology, taking into account the development of these areas in Latin America with the purpose of promoting and appropriating Nanotechnology in the region.

The CLACSA XIII is organized with the support of the Sociedad Latinoamericana de Ciencias de Superficie (SLACS), la Universidad de los Andes and Universidad Nacional in Bogotá-Colombia

PURPOSE

To serve as a forum for the exchange of information of research being conducted in the Americas on the physics of solid surfaces and related areas and material science, biomaterials and nano-scale phenomena and technology.

To stimulate collaborative research in this important and very active branch of science between researchers based in Latin America and those in the United States, Canada and Europe.

To promote further development of nanotechnology infrastructure in Latin America.

The conference will consist of plenary lectures, invited talks and oral presentations previously selected among the contributed papers. Poster sections are also planned with the main purpose of motivating discussions between senior physicists and young scientists of our region. We are stimulating the participation of graduate students mainly those developing their theses on topics related to the conference areas.
