Everything about Atomic Molecular And Optical Physics totally explained
Atomic, molecular, and optical physics is the study of
matter-matter and
light-matter interactions on the scale of single
atoms or structures containing a few atoms. The three areas are grouped together because of their interrelationships, the similarity of methods used, and the commonality of the
energy scales that are relevant.
Physicists sometimes abbreviate the field as
AMO physics. All three areas include both
classical and
quantum treatments.
Atomic physics
Atomic physics studies the
electron hull of
atoms. This branch of
physics is distinct from
nuclear physics, despite their association in the public consciousness. Atomic physics isn't concerned with the intra-nuclear processes studied in nuclear physics, although properties of the nucleus can be important in atomic physics (for example,
hyperfine structure). Current research focuses on activities in quantum control, cooling and trapping of atoms and ions, low-temperature collision dynamics, the collective behavior of atoms in weakly interacting gases (Bose-Einstein Condensates and dilute Fermi degenerate systems), precision measurements of fundamental constants, and the effects of electron correlation on structure and dynamics.
Molecular physics
Molecular physics focuses on multi-atomic structures and their internal and external interactions with matter and light.
Optical physics
Optical physics is distinct from
optics in that it tends to focus not on the control of classical light fields by microscopic objects, but on the fundamental properties of
optical fields and their interactions with matter in the microscopic realm.

External Link Exchanges
Do you know how hard it is to get a link from a large encyclopaedia? Well we're different and will prove it. To get a link from us just add the following HTML to your site on a relevant page:
<a href="http://atomic__molecular__and_optical_physics.totallyexplained.com">Atomic, molecular, and optical physics Totally Explained</a>
Then simply click through this link from your web page. Our crawlers will verify your link, extract the title of your web page and instantly add a link back to it. If you like you can remove the words Totally Explained and embed the link in article text.
As long as your link remains in place, we'll keep our link to you right here. Please play fair - our crawlers are watching. Your site must be closely related to this one's topic. Any kind of spamming, dubious practises or removing the link will result in your link from us being dropped and, potentially, your whole site being banned. |
