What are the main contributions to the matrix elements (intensity asymmetries with respect to normal emission) in ARPES?
Is there a theoretical paper on that?
 
Physics news on Phys.org
Do a search on Arun Bansil's papers. He and his collaborators have published a few papers on the matrix elements effects in ARPES spectra of high-Tc superconductors.

If you can't find them, I can do a quick search when I get into work tomorrow.

Thanks a lot.

But, I couldn't find any paper from this guy about matrix elements...

Only things about topological insulators...Can you provide a doi...?
 
Try using Google Scholar and search on "Bansil Photoemission". You'll find several papers, including this:

Lindroos et al. PRB v.65, p.054514.1 (2002), "Matrix element effects in angle-resolved photoemission from Bi2Sr2CaCu2O8: Energy and polarization dependencies, final state spectrum, spectral signatures of specific transitions, and related issues"

From the BCS theory of superconductivity is well known that the superfluid density smoothly decreases with increasing temperature. Annihilated superfluid carriers become normal and lose their momenta on lattice atoms. So if we induce a persistent supercurrent in a ring below Tc and after that slowly increase the temperature, we must observe a decrease in the actual supercurrent, because the density of electron pairs and total supercurrent momentum decrease. However, this supercurrent...
Hi. I have got question as in title. How can idea of instantaneous dipole moment for atoms like, for example hydrogen be consistent with idea of orbitals? At my level of knowledge London dispersion forces are derived taking into account Bohr model of atom. But we know today that this model is not correct. If it would be correct I understand that at each time electron is at some point at radius at some angle and there is dipole moment at this time from nucleus to electron at orbit. But how...
