Osciladores Paramétricos Óticos: para além do emaranhamento
Prof. Marcelo Martinelli
LMCAL – Instituto de Física – USP
Abstract:
O uso de osciladores paramétricos óticos como ferramenta multi-uso em ótica quântica deve-se ao conhecimento profundo que temos deste sistema desde meados dos anos 80, aliado à simplicidade de sua descrição. Esta aparente simplicidade vem do fato de que com cristais não-lineares podemos trabalhar em um regime de resposta linearizada do sistema, capaz de gerar estados comprimidos, ou dois campos emaranhado, ou até três campos emaranhados, a partir do acoplamento entre campos do bombeio e os campos convertidos em comprimentos de onda mais longos. Vamos mostrar que mesmo neste caso mais simples, podemos ter o emaranhamento de até seis modos do campo, em uma rede complex de emaranhamento. E vamos discutir como usando vapores atômicos em lugar de cristais podemos revelar uma nova região de exploração de efeitos além da aproximação linear.

Twisted and other non-conventional conjugated architectures: switching functionality from charge transport to photonic applications
Prof Peter Skabara
Ramsay Chair of Chemistry at the University of Glasgow
Abstract:
Keywords: Conjugated macromolecules, electron donors, oligofluorene, oligothiophene, charge transport
Summary: The synthesis and properties of some complex star-shaped conjugated architectures will be reported.
We have synthesised a series of well-defined, monodisperse oligothiophenes bearing a bridging, fused tetrathiafulvalene (TTF) unit and the much lesser known tetrathiocin heterocycle. The materials exhibit complex redox chemistry for longer conjugated analogues and they can be oxidised up to the octacation within a relatively narrow potential 
window. The methodology used to construct the end-capped oligothiophene chains has enabled us to explore a new range of Ge centred cruciform structures, in which the central bridging atom of the molecule provides a tetrahedral geometry. Whilst these materials are candidates for applications requiring good charge transport properties, we have also been investigating oligofluorene star-shaped structures for photonics and sensor applications and we report several series of new materials with multifunctional architectures. In this presentation we report on the synthesis, self-assembly and properties of these monodisperse macromolecules.
