However, if UCF Professor Enrique del Barco's observation can be fully understood and applied, scientists may have the basis to create quantum computers -- which could easily break the most complicated encryption in a matter of hours.
Unification theory with no extra dimensions. The first part unifies the strong nuclear force with the gravitational force in a mathematical way; the quantum vacuum is treated as a deformable system by the strong nuclear force. The second part unifies the nuclear force with the quantum vacuum in a hypothetical structure; the quantum vacuum is treated as a supersymmetric and metastable system with properties related to the different types of particles’ motion.
On May 16, 1960, American physicist Theodore Maiman presents the world's first operating laser at Hughes Research Laboratories, Malibu, California. Today, lasers are present everywhere, ranging from common consumer devices such as DVD players, laser printers, and barcode scanners to professional laser devices for surgery and various other skin treatments, or in industry for cutting and welding materials. Actually, it was Albert Einstein, who has laid the theoretical foundations for the laser in his 1917 paper Zur Quantentheorie der Strahlung (On the Quantum Theory of Radiation).
On August 8, 1902, English theoretical physicist Paul Adrien Maurice Dirac was born. Dirac is best known for his fundamental contributions to the early development of both quantum mechanics and quantum electrodynamics.
On October 7, 1885, Danish physicist and Nobel Laureate Niels Bohr was born. Bohr made foundational contributions to understanding atomic structure and quantum mechanics, for which he received the Nobel Prize in Physics in 1922.
Isn't it strange that our desire for newer and ever more dazzling media machines is equaled only by our wish to escape them? Innovations in media have always been driven by the desire to overcome mediation.
"We're going to shoot an ultraviolet laser into a (special type of) crystal, and out will come two. lower-energy photons that are entangled," Cramer said. For the first phase of the experiment, to be started early next year, they will look for evidence of
Open Journal of Physical Chemistry (OJPC) is an international journal dedicated to the latest advancement of physical chemistry. The goal of this journal is to provide a platform for scientists and academicians all over the world to promote, share, and discuss various new issues and developments in different areas of physical chemistry.
COLUMBUS is a collection of programs for high-level ab initio molecular electronic structure calculations. The programs are designed primarily for extended multi-reference (MR) calculations on electronic ground and excited states of atoms and molecules.
PyQuante is an open-source suite of programs for developing quantum chemistry methods. The program is written in the Python programming language, but has many "rate-determining" modules also written in C for speed.
A page run by the center for computational studies of electronic structure and spectroscopy of open-shell and electronically excited species. Links to educational material on quantum chemistry, a forum, and free software are found here.
Molden is a package for displaying Molecular Density from the Ab Initio packages GAMESS-UK , GAMESS-US and GAUSSIAN and the Semi-Empirical packages Mopac/Ampac, it also supports a number of other programs via the Molden Format. Molden reads all the required information from the GAMESS / GAUSSIAN outputfile. Molden is capable of displaying Molecular Orbitals, the electron density and the Molecular minus Atomic density.
This site contains details of various point-group symmetries, their inter-relations and specific information regarding dipole-transition selection rules.
cclib is an open source library, written in Python, for parsing and interpreting the results of computational chemistry packages. The current version parses output files from ADF, GAMESS (US), GAMESS-UK, Gaussian, Jaguar, Molpro, ORCA and Firefly.
Project summary
ESTEST (es-test) is a framework to facilitate the verification and comparison of Electronic Structure codes like Qbox, Quantum Espresso, Siesta, ABINIT, and The Exciting Code. The ESTEST framework consists of three components: automated input/output handling; translation to unified-representation (UR) XML format tools; rich web interface.
