Le prix Luckhurst-Samulski décerné à Pawel Pieranski


Le prix Luckhurst-Samulski, attribué chaque année au meilleur article publié dans Liquid Crystals, a été décerné à Pawel Pieranski et ses collaborateurs !

Extrait de l’éditorial de Liquid Crystals ,vol. 41, no 11, 2014 :

“I am delighted to report that the 2013 Luckhurst-Samulski Prize has been awarded to Pawel Pieranski and his colleagues for their paper entitled Generation of umbilics by magnets and flows. Geoffrey Luckhurst announced this decision and presented the Prize to Professor Pieranski at a ceremony held at the 25th International Liquid Crystals Conference held in Dublin, Ireland. This paper differs from the others on this year’s shortlist, and indeed from the previous prizewinners, by being essentially pedagogical and as such was considered by the Selection Committee to make an important contribution into the subject. The paper demonstrates beautifully the generation of defects in liquid crystals, their interactions with external fields and the visualization of magnetic fields by means of liquid crystals. It is an absolute pleasure to read and will clearly advance our understanding of a fascinating element of liquid crystal behaviour. I would strongly encourage everybody, irrespective of their scientific background, to read this paper.[…]”

Ombiliques générés de manière aléatoire

 

Cette expérience très simple peut servir à illustrer des sujets très variés : les cristaux liquides, le magnétisme, l’anisotropie optique, l’interférence de la lumière, les défauts topologiques dans des systèmes à symétrie brisée, etc.
