This splintered history, the theory goes, means that Ukraine is an artificial creation rather than a natural, coherent state.
Somalia ceased to be a coherent state in 1991, when its dictator, Siad Barre, was deposed by rebel militias.
The only way Ukraine can realise its European aspirations is over many years, by building an economically and politically coherent state.
"This is an incredibly impoverished country with no institutions, no economy and no cohesion; to expect a coherent state is to expect the impossible," Professor Dupont said.
That in turn will strengthen the argument that in the absence of a Saddam-like strongman Iraq, with its Sunni and Shia Arabs and Sunni Kurds, can never be a coherent state and must, at best, become a loose federation.
This is known as the Glauber coherent state which exhibits no conspicuous nonclassical effects.
Here, an input of a coherent state ((|alpharangle)) and squeezed vacuum ((|chi rangle)) is used.
Figure 7 The full experimental setup for the coherent state cavity mirror position estimation.
The uncorrelated, classical value is g 2 = 1 (obtained, for example, for a coherent state).
At this threshold occurs a phase transition from a disordered to a coherent state.
In Section 9, we obtain inversion formulas for both the coherent state transform and the K-averaged coherent state transform (Theorems 3, 4).
