The Question of Einstein`s Speculation E = mc2 and
... Note that the sum of two massless particles with respectively an equal but opposite momentum can generate a rest mass although the energy-momentum tensor of a massless particle is also traceless. Thus, a photon must consist of more than just electromagnetic energy. Fortunately, this is supported by ...

... only the spatial variables of the electrons whereas ̂ and ̂ are functions of the spin variables. Therefore, the latter operators trivially commute with ̂ . Hence the state functions of an atom must be eigenfunctions of ̂ and ̂ ; and as a result, can be labeled by the spin quantum numbers S and MS, i ...

... 3) For finite potentials, the wave function and its derivative must be continuous. This is required because the second-order derivative term in the wave equation must be single valued. (There are exceptions to this rule when V is infinite.) 4) In order to normalize the wave functions, they must appr ...

... 1. Ising ferromagnet: the Hamiltonian is invariant under all si → −si , whereas the low temperature phase has a spontaneous magnetization, and so is not. A convenient order parameter is the total average spin P S = i hsi i or the magnetization M = µS. This reflects the nature of the ordering (under ...
