... optical properties of quantum confined structures have been widely investigated [1-7]. Even since the advent of layered semiconductor structures, one of the main research interests has been the study of the optical properties of semiconductor quantum wells (QW). Not only have the optical properties ...
Spin Squeezing on an Atomic Clock Transition.
... a probe laser. (b) Atomic level structure. The resonator is tuned such that atoms in the two clock states produce equal and opposite resonator frequency shifts via the state-dependent atomic index of refraction. (c) Preparing a squeezed input state for an atomic clock. A number-squeezed state (iii) ...

DIPLOMA THESIS Classical Chaos in Collective Nuclear Models
... Atomic nuclei are many particle objects and in general typical examples of nonintegrable systems1 . They were historically the first physical systems in which spectra with properties typical of chaotic dynamics2 were observed and studied. Chaotic behaviour of nuclei may be studied in both single par ...

Orbital order in classical models of transition
... Conclusion. – We have demonstrated that the classical 120◦ -model exhibits long-range order at sufficiently low temperatures. The key feature is that the degeneracy of the ground states is broken at positive temperatures via a kind of “order-by-disorder” mechanism. A complete argument, on a level of ...
