Kelvin: l’échelle du froid
Zéro Kelvin, c’est le zéro absolu de la température. Comme la chaleur est de l’énergie, le froid, lui, est synonyme d’énergie moindre. Mais il n’existe pas d’énergie négative. Exprimé sur l’échelle Celsius qui nous est familière, zéro Kelvin (0 K) correspond à – 273,15 degrés Celsius: rien ne peut être plus froid. Certains scientifiques du PSI réalisent des expériences à basses températures, proches de ce chiffre; d’autres bricolent pour abaisser la température le plus efficacement possible.
«Dans la recherche quantique, les coopérations sont tout à fait cruciales»
Kirsten Moselund, chercheuse au PSI, évoque pour nous les technologies quantiques, notamment leur importance et l’état actuel de la recherche en Suisse. Elle nous parle également de ses propres recherches dans le domaine de la nanophotonique.
Un laser dessine des paysages magnétiques sur mesure
Des scientifiques du PSI ont découvert une méthode étonnamment rapide et bon marché pour modifier localement des matériaux magnétiques.
Comment les microtubules participent au traitement des signaux cellulaires
Des scientifiques du PSI ont étudié, au niveau moléculaire, la manière dont le cytosquelette transmet des ordres vers l’intérieur de la cellule. Leurs résultats pourraient offrir à la médecine de nouvelles possibilités d’intervention en cas de dysfonctionnement dans l’organisme.
