For borne away in deadened air
May go the sudden shut of loss
Round something nearly at an end,
And what cohered in it across
The years, the unique random blend
Of families and fashions, there
"Ambulances" by Philip Larkin

And all preparation is for it! and identity is for it! and life and
materials are altogether for it!

In science:

In this section we define a (g, a)-coherent family and show that every simple g-module M is a submodule of a unique semisimple coherent family Ea(M ).
On the structure and characters of weight modules
For an a-bounded g-module M, a (g, a)-coherent extension E of M is a (g, a)coherent family which contains M as a subquotient and dega M = dega E .
On the structure and characters of weight modules
The coherent tunneling of electrons entails coherence between the wells, as will be discussed in Sec. 9.
Broken Symmetry and Coherence of Molecular Vibrations in Tunnel Transitions
This may seem rather restrictive, but since the homogeneous condensate oscillates coherently with a frequency larger than the Hubble expansion rate during the initial stages of preheating, the only relevant time scale is the mass of the coherently oscillating field.

Isomorphism problem for finitely generated fully residually free groups
Multi-photon signals together with loss in the optical fiber can threaten security, but proofs of security for QKD using weak coherent states have been found [9,10]. (We note that for QKD protocols that use decoy states [11–14], security can be proven even for rather strong coherent-state signals.
Phase randomization improves the security of quantum key distribution
In d = 1 and d = 2, the fully coherent system is always strongly localized, whatever the strength of the disorder is. 3The effective dimension of the system is obtained by comparing the sample size with the phase coherence length Lϕ .

And the defining property for coherent states associated to oscillators is that they are eigenstates of the annihilation operator with the eigenvalue given by the label of the coherent states.
On the Construction of Generalized Grassmann Coherent States
The major attention of the book is focused on the mechanisms that guarantee boundedness and coherence in the physical systems. I put forward crucial arguments that they cannot be integrated coherently in any of the existing so far approaches.
Fluctuations and Long-Term Stability: from Coherence to Chaos
Thus, the rest of the book justifies the second part of our title: From Coherence to Chaos. Further, the premises and the details of the coherence are considered in Chapters 4, 5 and 6.
Fluctuations and Long-Term Stability: from Coherence to Chaos
Now we come to the question about the properties that make a media suitable for providing coherence. Our daily experience teaches that we cannot fit everything everywhere. However, now we are interesting in those properties of the media that ensure coherence.
Fluctuations and Long-Term Stability: from Coherence to Chaos
Now I am ready to discuss the central issue of the present chapter, namely how the coherence provides stabilization. Let us recall that the implement of the coherence, the non-local feedback, has the specific property to couple more and more “flexible” Hamiltonians on decrease of the colliding energy.
Fluctuations and Long-Term Stability: from Coherence to Chaos
In addition, I should stress on the point that neither system subject to coherence can reach thermodynamical equilibrium because the coherence makes the states associated with different selections equiprobable.
