Nope, I just look for a method to prove it mathematically

Thanks for your help

Hi, I would like to verify analytically that a vector potential of the form A=1/2(-yB0,xB0,0) produces a constant magnetic flux density of magnitude B0 in the z direction. (I guess I'd have to use the relation B=\forall\wedgeA...)

Hey, I'm looking for a method for calculating the wave vector of a polariton mode with a given frequency f knowing the static and high frequency dielectric constants of InP (\epsilonst and \epsilon\infty) and the TO phonon frequency \upsilonTO. Thanks for your help! S.

Hi, I need some help to work out the electron-hole overlap integral Mnn' for a quantum well: Knowing that M'nn'=\int\varphi*en'(z).\varphihn(z).dz => How can I show that Mnn' is unity if n=n' and zero otherwise (in a quantum well with infinite barriers) ? => How can I show that Mnn' is zero...

Found it! http://www.projectrho.com/rocket/futurelang.php Thank you very much! ;D

? I don't think I really get your advice...

Wow, that's precious! Thank you very much, how did you find these sources? I just need to find some data about the band structure of the materials used and I'll have all I want, could you tell me by what means you got these websites/pages? Thank you so much

More of a brain teaser... I didn't discover anything, unfortunately! (yet! ;D)

Hi, Do someone have a clue on how to answer that? : An anomalous bright red spectral emission line has been detected in the nearby solar-type star GL1023. The brightness of the feature sometimes suddenly changes by a factor 2 with a frequency of 0.92Hz. After about 10 min of these...

Hi everybody, I would like to know if someone could explain to me what happens to the refraction index of gold at grazing angle (X-ray applications), and particularly the band structure explanation (if you have it!)... Indeed, I heard that the x-ray telescopes were made of parallel mirrors...

Hi, I'm looking for papers and general or specific information about the topic Astronomy in UV and X-ray Spectrum. Other than Wikipedia and Google sources, I would be interested in understanding the optical spectrum range and its limits, with respect to the materials used in this astronomy...

That's a bit too much "not too theoretical"... But thank you though, if you think about anything else... Thanks a lot

Hi everyone, I'm trying to gather some ideas of subjects for an oral presentation in my Optical Properties of Materials class: I'd love to find something pleasant or at least nice to develop (like I heard "how a cameleon changes color?"^^), not too theoretical if possible... And with some...
