Hello Everyone! I need help on this topic. Can anyone provide me some details on how to solve the problem? Thanks..
 
Physics news on Phys.org
As I recall, the hydrogen molecule (and maybe also the hydrogen molecular ion) problems are solved in the quantum mechanics book by Pauling and Wilson.

As an aside, the best method (as in - most accurate for the computational complexity) is the now seldom-seen Hylleraas variational approach (applied to helium in 1929), which works for two electrons but not that well for many more. The method was used to calculate hydrogen http://scitation.aip.org/getabs/servlet/GetabsServlet?prog=normal&id=JCPSA6000001000012000825000001&idtype=cvips&gifs=yes" , with a result that was far better than perturbatory calculations could do at that time.

Hey thanks for the link. I think the file has the information i need. Unfortunately i don't have an access to download the file. =) Just in case you have another link to that file perhaps you can post it. =)

Thanks! I just borrowed that book and I will read it. I'll try to understand the book. I will post some questions just in case I can't understand some parts of it. =) Thanks again. Just in case you have any other info about the topic, please feel free to post it because it would really be a great help. =)
 

Thread 'Stability of persistent currents in superconductors regardless of temperature'

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...

Thread 'Instantaneous dipole moment and orbitals'

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...
