... where ¼ 2g2 = is the phonon-mediated spin-spin coupling strength. Rewriting Jþ J ¼ J2 Jz2 þ Jz , and provided the total angular momentum J is conserved, we obtain a term / Jz2 corresponding to the one-axis twisting Hamiltonian [30]. To generate a spin squeezed state, we initialize the ensemble ...

Langer`s Method for the Calculation of Escape Rates
... Smaller particles are magnetically more unstable than larger particles [32], this fact can be attributed to the fact that surface effects are more pronounced in smaller particles, since, as their size decreases, their surface to volume ratio increases. So, the size of a particle itself, that is, the ...

quantum theory of atoms, molecules and their interaction with light
... There are several problems (˜60) embedded in the text, and their solution is strongly recommended for the students. In view of the author this is a necessary condition for getting a reliable knowledge of the subject, as is the case with any other physics subject. The electronic form made it possible ...

Un-topical review Heisenberg`s dog and quantum computing
... with an uncertainty of 10 ft s (the exponent is fuzzy), the dog’s position became so uncertain that it was impossible to tell the dog from its fuzz.5 The velocity uncertainty originates, of course, in the random up-and-down and side-to-side motion of the dog’s tail (incidentally, an early manifestat ...

Mass-spectrum of Charged Leptons from the Planck Mass
... In 1952, Nambu [5] proposed a unit of mass MN = me / α ≈ 137 me, where me is the electron mass and α is the fine-structure constant. He suggested that the mass of a particle can be written as m(N) ≈ N MN , where N is “mass number,” which can be either integer {0, 1, 2 ...} or half-integer {1/2, 3/2, ...

Attenuation of gamma particles

In Compton scattering, the gamma particle is scattered out of the beam with a lower energy. Thus, I(x) in Lambert’s law refers to the ...
