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.
Loading a vapor cell magneto-optic trap using light-induced atom desorption
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.” .
Discovery of the Cerium Isotopes
FIG. 14: The solid line gives a parametric plot of the critical atom number, N0 , and the saturation photon number, n0 , for fused-silica microspheres and the D2 transition of atomic Cesium, incorporating the loss mechanisms outlined in section IV.
