In science:

Narrow-bandwidth biphotons are ideal for a number of recently proposed protocols for long-distance quantum communication based on coherent interaction between single photons and atomic ensembles [14, 15], which require efficiently absorbing biphotons and storing the entanglement.
Narrow-Band Biphoton Generation near Atomic Resonance
Here νk (t) is the number of clusters containing k copper atoms, Vs is the simulation volume, Rk is defined similarly to Eq. (3): Rk = a(3k/8π)1/3 , and sums over k in (14) include only clusters with k ≥ Nc where Nc is the “critical” size chosen.

Achieving the Quantum Ground State of a Mechanical Oscillator using a Bose-Einstein Condensate with Back-Action and Cold Damping feedback schemes
The evaporative cooling techniques used to achieve Bose-Einstein condensation in atomic gases [1–4] rely on loading large numbers of atoms into magnetic traps with long trap lifetimes.

During this process the two capping atoms are also drawn closer to the central atom to form new contacts, thus giving the central atom a coordination number of 14.
Identifying structural patterns in `disordered' metal clusters
The criteria for the discovery of an element were established in 1991: “Discovery of a chemical element is the experimental demonstration, beyond reasonable doubt, of the existence of a nuclide with an atomic number Z not identified before, exiting for at least 10−14 s.” .
