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 quintillion) of a second. An attosecond is to a second as a second is to about 31.71 billion years.
Oct 3, 2023 · The Nobel Physics Prize was awarded on Tuesday to three scientists for their work on attoseconds, which are almost unimaginably short periods of time.
Oct 4, 2023 · “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...
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 matter with unprecedented time resolution.
Oct 4, 2023 · "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...
Oct 3, 2023 · Attosecond physics allows scientists to look at the very smallest particles at the very shortest timescales (an attosecond is one-quintillionth of a second, or one-billionth of a nanosecond)....
Oct 10, 2023 · 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 are seconds in the age of the universe. An attosecond is incredibly small when compared to a second.
