Atoms and Molecules

Atoms and Molecules

An atom is a system formed by a pack of electrically charged particles Q called nucleus and N identical particles of charge q − . Molecules are systems with several nuclei which may not necessarily be identical . In almost all matter, the nuclei are conglomerates of neutrons and protons and the N remaining particles are electrons. Other atomic systems will be described in the exotic atoms section.

Quantum Mechanics of Atoms & Molecules

These are a set of notes I have made, based on lectures given by Y.Xian at the University of Manchester Jan-June ’08. Please e-mail me with any comments/corrections: [email protected].

Ultrafast Electron Diffraction of Atoms and Molecules

A new scientific instrument at the Department of Energy's SLAC National Accelerator Laboratory promises to capture some of nature's speediest processes. It uses a method known as ultrafast electron diffraction (UED) and can reveal motions of electrons and atomic nuclei within molecules that take place in less than a tenth of a trillionth of a second – information that will benefit groundbreakin...

Entanglement Computation in Atoms and Molecules

In this paper, a method for computing entanglement of electrons in atoms and molecules is described. The importance of entanglement computation for Quantum Computers and for Biology is highlighted and the existing models’ pros and cons are illustrated. A description of the algorithms follows, with some considerations about the execution times and how they scale increasing the system’s Hilbert s...
