Programming scale-free optics in disordered ferroelectrics [PDF]
Jacopo Parravicini, Claudio Conti, Aharon J. Agranat, Eugenio DelReUsing the history-dependence of a dipolar glass hosted in a compositionally-disordered lithium-enriched potassium-tantalate-niobate (KTN:Li) crystal, we demonstrate scale-free optical propagation at tunable temperatures. The operating equilibration temperature is determined by previous crystal spiralling in the temperature/cooling-rate phase-space.View original: http://arxiv.org/abs/1207.0683
