Random quasi-phase-matching in bulk polycrystalline isotropic nonlinear materials
Article Abstract:
A study is conducted to show that exploiting the random motion of the relative phases in highly transparent polycrystalline materials can be an effective strategy for achieving efficient phase matching in isotropic materials. Distinctive features of this random quasi-phase-matching approach are a linear dependence of the conversion yield with sample thickness and the absence of the need for either preferential materials orientation or specific polarization rules among others.

A superfluid in born
Article Abstract:
Researchers have conducted experiments for describing at how a phase transition similar to, but slightly different than the gas-liquid transition, occurs the birth of a superfluid droplet. The birth and initial growth of a Bose-Einstein condensate is described by using these experiments.
