Talk:Jellium

Thompson's model

Someone should mention that the Jellium model conforms to Thompson's 'plum pudding' model. Since it was Thompson's calculations that were the basis for this one. —Preceding unsigned comment added by 149.119.156.205 (talk) 21:37, 29 May 2009 (UTC)

Lack of symbol definition

Many symbols in the equations are just not defined. Even if some symbols are conventional, they should be defined. What is q for example? —Preceding unsigned comment added by 129.194.8.8 (talk) 09:35, 7 September 2010 (UTC)

Etymology

I am curius about the origin of the term jellium. Can it be referenced in a historical context? Would be nice if someone could add some info. — Preceding unsigned comment added by 141.14.162.129 (talk) 13:03, 2 May 2014 (UTC)

I've always assumed it's just a reference to jelly / jell-o / Gelatin dessert, i.e. something that clearly has no internal structure, as noted in the third paragraph of the article. Djr32 (talk) 17:36, 2 May 2014 (UTC)

Jellium as an optical reflector

The metallic nature of jellium means that it should reflect photons like a metal mirror (for photon energies less than the absorption band gap of the metal). Can anyone provide the fraction of photons reflected by a thin 2D layer of jellium in terms of the free electron concentration per square cm? Steve scint (talk) 01:17, 30 August 2022 (UTC)

The optical reflectance R of a very thin sheet of Jellium of thickness T (cm) and free electron concentration C (per cm3) should be described by R = SCT where S is the free electron cross section (cm2). How can one calculate S in the Jellium model? Steve scint (talk) 14:15, 3 September 2022 (UTC)
