Energy levels
Sorry for deleting your comments about changing energy levels. I'm not familiar with quantum chemistry, only quantum field theory. Phys 22:57, 3 April 2005 (UTC)

Untitled 1
I thought the top section of this article in the references to field theory, quantum chemistry and ladder operators was somewhat misleading. Generally in quantum chemical papers, creation and annihilation operators refer to creation and annihilation of an electron, and in solid state papers its can be an electron or a hole depending on the context.

Creation and annihilation operators are useful notations in the whole quantum mechanics see for example harmonic oscillator. Nevertheless they play a particular role in Quantum Field Theory since they are the basis for the second quantization. However they don't play a particular role in Quantum Chemistry at least not more than in Solid State Physics or Plasma Physics or Many-Body Physics.--147.231.28.83 09:49, 29 August 2005 (UTC)
Edited the fourth math-line on this page to improve readability
I entered this article first time a few weeks ago, while preparing a seminar presentation on semiconductor lasers. The text here is an excellent reference for people like me who do not use quantum mechanical formulation as an everyday routine, but have studied it possibly a few years earlier. I was astonished about the comment, "This article may require cleanup". To me the weakest point was on the fourth math line of the article. I found that the readability could be improved with a minor modification, that I made. Regards, Juha Viljanen 195.165.83.2 12:20, 19 January 2006 (UTC)
