Hi y'all, I have always heard of the word "condensed matter physicsts" here and there. Unitil recently, however, I realized that I have no idea what it means! What do condensed matter physicists do? What kind of things do they study? How is condensed matter physics different from QM or GR?

They do all of what used to be called "solid state physics"--the study of solids, superconductivity, semiconductors, magnetic materials, etc.--plus areas like fluids, superfluids, Bose-Einstein condensates and nanotechnology. Others who work in this area can add to the list but you probably get the idea.

A separate "new" category is soft matter physics, which is the study of polymers, membranes (biological, not the 'branes of cosmology), proteins, gels and so on.

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...
