Anderson localization: The role of quantum symmetries
December 10th, 2014UncategorizedMarcella Bonifazi 0 Comments

Fifty years after the discovery of Anderson localization, the influence of disorder continues to surprise. In 1958, the US physicist P. W. Anderson discovered the phenomenon of disorder-induced localization while pursuing a general theory of electron transport. Anderson predicted for the first time that disorder can arrest the transport of energy in random systems through […]

Harvesting energy from chaos
December 5th, 2014Research highlights, UncategorizedMarcella Bonifazi 0 Comments

Chaos is a phenomenon that occurs in many aspects of contemporary science. In classical dynamics, chaos is defined as a hypersensitivity to initial conditions. The presence of chaos is often unwanted, as it introduces unpredictability, which makes it difficult to predict or explain experimental results. Conversely, we demonstrate here how chaos can be used to […]

Biological cybernetics: period doubling via nonlinear stocastic resonance
December 2nd, 2014Research highlights, UncategorizedChangxu Liu 0 Comments

Rhythms of life are dictated by oscillations, which take place in a wide rage of biological scales. In bacteria, for example, oscillations have been proven to control many fundamental processes, ranging from gene expression to cell divisions. In genetic circuits, oscillations originate from elemental block such as autorepressors and toggle switches, which produce robust and […]

Nanocpp is a comprehensive FDTD suite, written with state-of-the-art C++ techniques, for the ab-initio parallel simulations of Maxwell’s equations. It is designed to scale up to hundreds of thousands of processors, like BBMD. Some of the features of Nanocpp are: 2D and 3D FDTD within a single interface UPML TFSF Plane wave + TFSF realistic […]

GZILLA: ab-initio MD + TDDFT + FDTD
June 1st, 2011UncategorizedJuan Sebastian Totero Gongora 0 Comments

      XFEL sources are extremely revolutionary, and their study requires a revolutionary code, as well. After one year of work, I coded GZILLA, one of the most comprehensive ab-initio simulator ever realized. GZilla is composed of more than 120000 lines of MPI parallel code. Its analysis capabilities range from DFT ground state, to […]

BBMD: Molecular dynamics beyonds the limits

Recently, contributing to the 2009 annual survey of the EDGE foundation entitled “What will change everything”, T. Sejnowski foresees that the computers will be the “microscopes of the future” and, specifically, that are computers that “have made it possible to localize single molecules with nanometer precision and image the extraordinary complex molecular organization inside cells”. […]
