Atoms and molecules in soft confinement potentials

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.

Enzyme molecules in solitary confinement.

Large arrays of homogeneous microwells each defining a femtoliter volume are a versatile platform for monitoring the substrate turnover of many individual enzyme molecules in parallel. The high degree of parallelization enables the analysis of a statistically representative enzyme population. Enclosing individual enzyme molecules in microwells does not require any surface immobilization step an...

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...

Detecting electron motion in atoms and molecules.

The detection of spatial and temporal electronic motion by scattering of subfemtosecond pulses of 10 keV electrons from coherent superpositions of electronic states of both H and T2(+) is investigated. For the H atom, we predict changes in the diffraction images that reflect the time-dependent effective radius of the electronic charge density. For an aligned T2(+) molecule, the diffraction imag...
