An attosecond (abbreviated as as) is a unit of time in the International System of Units (SI) equal to 10 −18 or 1 ⁄ 1 000 000 000 000 000 000 (one quintillionth) of a second. [1] An attosecond is to a second, as a second is to approximately 31.69 billion years. [2]

2023年10月4日 · “Atto” is the scientific notation prefix that represents 10 -18, which is a decimal point followed by 17 zeroes and a 1. So a flash of light lasting an attosecond, or 0.000000000000000001 of a...

2023年10月3日 · French physicist Anne L'Huillier was the first to discover a tool to pry open the world of attoseconds. The Nobel Physics Prize was awarded on Tuesday to three scientists for their work on...

2023年10月10日 · By providing shorter snapshots of atoms and molecules, attosecond spectroscopy has helped researchers understand electron behavior in single molecules, such as how electron charge migrates and how chemical bonds between atoms break.

2023年10月4日 · Attoseconds are the scale at which electrons travel around their atoms. (A Luna Blue/Verve+/Getty Images) The Nobel Physics Prize was awarded on Tuesday to three scientists for their work on attoseconds, which are almost unimaginably short periods of time.

Attosecond physics, also known as attophysics, or more generally attosecond science, is a branch of physics that deals with light-matter interaction phenomena wherein attosecond (10 −18 s) photon pulses are used to unravel dynamical processes in …

2023年10月4日 · So a flash of light lasting an attosecond, or 0.000000000000000001 of a second, is an extremely short pulse of light. In fact, there are approximately as many attoseconds in one second as there...

An attosecond (as) is a very short period of time. [1] It is equal to one quintillionth of a second (or 0.000000000000000001 seconds). It can also be written as 10 −18 seconds.

2012年9月18日 · To understand the movements of electrons, and eventually those of subatomic particles, requires attaining the attosecond and ultimately zeptosecond (sextillionths of a second) range, Kaertner says.

2023年10月6日 · An attosecond is one billionth of a billionth of a second. • An attosecond is so short that the number of them in one second is the same as the number of seconds that have elapsed since the universe came into existence, 13.8 billion years ago.
