Recent Applications of X Rays in Condensed Matter Physics

ince their discovery by Wilhelm Conrad Rontgen, x rays «Jhave played a significant role in our lives: they make the unseen in our bodies visible; they enhance our security in air travel; they make possible nondestructive testing of a wide variety of materials. And through x-ray diffraction and spectroscopy they make it possible to probe the order of matter at the atomic level. The discovery of ...

The key insight of Bogoliubov is that although the mean-field Hamiltonian (1) is clearly not diagonal in the space of states created by the operators ck,↑/↓, it may be diagonal in a basis of states created by operators related to these via a simple SU2 transformation. Indeed, it may be the case that ‘electrons’ and ‘holes’ are the wrong degrees of freedom to consider; we should at least look to...
