Attosecond science
Scientists have been developing sources of light with ever-shorter pulse durations, in order to study motion in systems ranging from a golfer’s swing to the motion of atoms within molecules. The shortest pulses produced to date are under 60 attoseconds, i.e. 60 × 10−18 s. One attosecond is to one second as one second is to the age of the universe. For comparison, the classical orbital period of...
متن کاملAdvances in attosecond science
Attosecond science offers formidable tools for the investigation of electronic processes at the heart of important physical processes in atomic, molecular and solid-state physics. In the last 15 years impressive advances have been obtained from both the experimental and theoretical points of view. Attosecond pulses, in the form of isolated pulses or of trains of pulses, are now routinely availa...
متن کاملAttosecond and Angstrom Science
When a strong laser field ionizes atoms (or molecules), the electron wave packet that tunnels from the molecule moves under the influence of the strong field and can re-collide with its parent ion. The maximum re-collision electron kinetic energy depends on the laser wavelength. Timed by the laser field oscillations, the re-colliding electron interferes with the bound state wave function from w...
متن کاملFundamentals of Neurogastroenterology: Basic Science.
This review examines the fundamentals of neurogastroenterology that may underlie the pathophysiology of functional GI disorders (FGIDs). It was prepared by an invited committee of international experts and represents an abbreviated version of their consensus document that will be published in its entirety in the forthcoming book and online version entitled ROME IV. It emphasizes recent advances...
متن کاملAttosecond science: recent highlights and future trends.
We review the first ten years of attosecond science with a selection of recent highlights and trends and give an outlook on future directions. After introducing the main spectroscopic tools, we give recent examples of representative experiments employing them. Some of the most fundamental processes in nature have been studied with some results initiating controversial discussions. Experiments o...
