Billiards, both quantum and classical, have been applied in several areas of physics to model quite diverse real world systems. Examples include ray-optics , [ 10 ] lasers , [ 11 ] [ 12 ] acoustics , [ 13 ] optical fibers (e.g. double-clad fibers [ 14 ] [ 15 ] ), or quantum-classical correspondence. [ 16 ]
Pentanedione may refer to: Acetylacetone (2,4-pentanedione) Acetylpropionyl (2,3-pentanedione) See also. C 5 H 8 O 2; Cyclopentanedione
Acetylacetone is an organic compound with the chemical formula CH 3 −C(=O)−CH 2 −C(=O)−CH 3.It is classified as a 1,3-diketone.It exists in equilibrium with a tautomer CH 3 −C(=O)−CH=C(−OH)−CH 3.
From 1990 until 1993 a process was underway which split the journal then entitled Physical Review A: General Physics into two journals. Hence, from 1993 until 2000, one of the split off journals became Physical Review E: Statistical Physics, Plasmas, Fluids, and Related Interdisciplinary Topics. In 2001 the journal was changed, in name, to its ...
An acoustic pipe, such as an organ pipe, marimba, or flute resonates at a specific pitch or frequency. Longer pipes resonate at lower frequencies, producing lower-pitched sounds. The details of acoustic resonance are taught in many elementary physics classes. In an ideal tube, the wavelength of the sound produced is directly proportional to the ...
The term ordinary Hall effect can be used to distinguish the effect described in the introduction from a related effect which occurs across a void or hole in a semiconductor or metal plate when current is injected via contacts that lie on the boundary or edge of the void. The charge then flows outside the void, within the metal or semiconductor ...
Exchange interaction is the main physical effect responsible for ferromagnetism, and has no classical analogue. For bosons, the exchange symmetry makes them bunch together, and the exchange interaction takes the form of an effective attraction that causes identical particles to be found closer together, as in Bose–Einstein condensation .
Faraday's ice pail experiment is a simple electrostatics experiment performed in 1843 by British scientist Michael Faraday [1] [2] that demonstrates the effect of electrostatic induction on a conducting container. For a container, Faraday used a metal pail made to hold ice, which gave the experiment its name. [3]
