One peek at the ion isn’t enough; scientists checked repeatedly if the calcium ion was bright or dark, proving that they had ...

Researchers used atomic clock laser methods and a helper calcium atom to control a calcium monohydride molecule, expanding ...

Researchers have achieved real-time capture of the ionization process and subsequent structural changes in gas-phase molecules through an enhanced mega-electronvolt ultrafast electron diffraction (MeV ...

They are literally channels for communication: Pore-forming proteins in living cells, termed ion channels, are embedded in the outer membrane of almost all cell types and play a crucial role in the ...

A view inside the trapped-ion quantum computer that carried out a first-of-its-kind simulation of molecular chemistry. A single atom has performed the first full quantum simulations of how certain ...

This image depicts the radium atom’s pear-shaped nucleus of protons and neutrons in the center, surrounded by a cloud of electrons (yellow), and an electron (yellow ball with arrow) that has a ...

Cold ion-atom interactions represent a rapidly evolving field that merges atomic physics, quantum chemistry and many-body dynamics. In ultracold environments, ions and neutral atoms engage in ...

A single atom has performed the first full quantum simulations of how certain molecules react to light. The researchers who carried out the feat say that their minimalistic approach could dramatically ...

Earlier theories had forecast an appreciable drop in the reaction probability at low temperatures, but we could not confirm this either in the experiment or in new calculations by our colleagues on ...

For the experiment, an intense femtosecond ultraviolet laser pulse was employed to induce resonance-enhanced multiphoton ionization in 1,3-dibromopropane (1,3-DBP) molecules. The picosecond and ...
