Diffraction  

In General > s.a. scattering; wave phenomena.
* Idea: The spreading of a wave interacting with a scatterer or slit; In the context of semiclassical mechanics, it describes the manner in which quantum mechanics smooths over discontinuities in classical mechanics.
* History: In the 1660s, Grimaldi observed an alteration of color in shadows.
@ History: Saatsi & Vickers BJPS(11) [inconsistency and untruth in Kirchhoff's theory].

Special Effects > s.a. radiation; Talbot Effect.
* Kapitza-Dirac effect: The diffraction of a well-collimated particle beam by a standing wave of light; There are plans to use it to build an electron interferometer 10,000 times more sensitive than ones based on light.
@ Kapitza-Dirac effect: Batelaan CP(00)qp; Freimund et al Nat(01)sep; Marshall FP(06)qp/04 [for atoms, interpretation]; Batelaan RMP(07) [two-color version]; > s.a. electron [charge density probe].
@ Rayleigh limit: Rueckner & Papaliolios AJP(02)jun [demo]; Tamburini et al PRL(06)ap [overcoming, light orbital angular momentum]; > s.a. optical technology.
@ Beating the diffraction limit: news nat(11)jul [for sound waves]; > s.a. microscopes.
@ Diffraction-free light beams: Durnin et al PRL(87) [Bessel beams]; > s.a. Airy Beams.
@ Anomalous photon diffraction: Cardone et al PLA(04) [non-Lorentzian].
@ QED calculations: Daniels et al a1612; Stöhr a2003 [diffraction in second-order QED and the quantum nature of light].
@ Related topics: Firstenberg et al PRL(09) + Novikova Phy(09) [reducing diffraction]; Saltiel et al PRL(10) [non-linear diffraction from a virtual beam]; news pw(14)oct [butterfly-wing-inspired material and "reverse diffraction"].

Diffraction in Time > s.a. dissipation.
* Idea: Diffraction of matter waves observed with a time-domain aperture (such as an absorbing barrier or "shutter" that is periodically switched on and off).
