Sat, 27 May 2017 21:43:36 +0000HUBzero - The open source platform for scientific and educational collaborationIn physics, the WKB (Wentzel–Kramers–Brillouin) approximation, also known as WKBJ (Wentzel–Kramers–Brillouin–Jeffreys) approximation, is the most familiar example of a semiclassical calculation in quantum mechanics in which the wavefunction is recast as an exponential function, semiclassically expanded, and then either the amplitude or the phase is taken to be slowly changing.
This method is named after physicists Wentzel, Kramers, and Brillouin, who all developed it in 1926. In ...nanoHUB.orgsupport@nanohub.orgnonanoelectronics, quantum mechanics, WKB Approximation, AQMEDragica Vasileskaen-gbCopyright 2017 nanoHUB.orgResources
