Solitonization of Anderson localisation and optical-event horizons

In a paper in arXiv, Mohammed F. Saleh, Claudio Conti and Fabio Biancalana show that the solitonization of the Anderson localization and the formation of optical horizons by cluster of solitons explain the rogue-solitons in supercontinuum generation.

MRS Fall : Tailored Disorder

11 February 2018

We are announcing the Tailored Disorder Symposium at the MRS (Material Research Society) Fall Meeting 2018 Disorder and perturbed periodicity in materials are in the process of becoming a vital research area that has started to show that optical media do not necessarily have to be regular. Photonic materials with deliberately introduced disorder in their respective geometries and compositions show interesting novel and tunable unforeseen properties. So far, countable scientific achievements have been reported in the areas of biology, materials science, nano-optics and -photonics that, however, already point towards a wealth of interesting effects with several applicative dimensions.

Quantum Gravity Slingshot

10 May 2018

Modified uncertainty principle and non-commutative variables may phenomenologically account for quantum gravity effects, independently of the considered theory of quantum gravity. We show that quantum fluids enable experimental analogs and direct tests of the modified uncertainty principle expected to be valid at the Planck scale. We consider a quantum clock realized by a long-lasting quantum fluid wave-packet orbiting in a trapping potential.
