... vacuum state” in which the fluctuations of the quadrature components Xk,λ or Yk,λ are less than in the vacuum state. The squeezed vacuum state was obtained by acting a “squeeze operator” Ŝ(ξ) on the vacuum state |0i. In this exercise (as in Ex. 5.8) we will consider a single mode only and drop the ...

... of the atom with point-charge electrons, does not give results in agreement with experiment. The discrepancies consist of " duplexity " phenomena, the observed number of stationary states for an electron in an atom being twice the number given by the theory. To meet the difficulty, Goudsmit and Uhle ...
Self-consistent approach for calculations of exciton binding energy
... Presently, the best results are usually obtained within the framework of the variational approach, where a certain form of the exciton wave function, depending on one or more variational parameters is being postulated. The exciton energy is then calculated by minimizing the respective energy functio ...

This is in contrast to liquid helium in which the quantum depletion is about 90 %. The phase of the condensate and the coherence properties of ...

Aberration-Corrected Analytical Electron Microscopy of Transition Metal Nitride and Silicon Nitride Multilayers
... A sub category of coatings are thin films where the thickness is less than a couple of micrometers and can be made as thin as a few, or even single, atomic layers. Such thin coatings can be found in everyday objects such as mirrors, where the reflection is enabled by the thin metallic layer on the b ...

Atomic Structure and the Periodic Table
... In the few years following the announcement of the Bohr theory, a series of revisions to this model occurred. Bohr’s single quantum number (n) was expanded to a total of four quantum numbers (n, l, ml , ms). These quantum numbers were necessary to explain a variety of evidence associated with spectr ...
