Under sportlovet anordnade Fysikum, Vetenskapens hus och Kungliga vetenskapsakademien en så kallad ” Science meetup” som riktar sig till gymnasieelever och främst till nyanlända ungdomar. Idén bakom projektet är att hjälpa de nyanlända ungdomarna in i det svenska samhället genom interaktion med svenska ungdomar.
Superconductivity is caused by pairing of electrons (formation of Cooper pairs). Usually the required electron-electron interaction is mediated by phonons –vibrations of positive ions in the crystal lattice. In this case Nature finds a smart way of avoiding direct Coulomb repulsion of equally charged electrons in the pair.
Liquid water fluctuates between two different states when it is cooled and these fluctuations reach a maximum at -44 oC. An international team of researchers headed by the Stockholm University reported the first experimental evidence of the existence of the Widom line which is supposed to emanate from the liquid-liquid critical point.
The ion trapping group at Stockholm University led by Markus Hennrich has implemented the first quantum gate on a trapped Rydberg ion. The result has been published in Physical Review Letters and has been highlighted as an editors’ suggestion.
There is a range of wavelength in the electromagnetic spectrum that is hard to exploit, although it would certainly bring enormous advantages in many fields of application if we were able to build a suitable source. That is known as the THz Gap (The Terahertz Gap), and researchers at Stockholm University seem to have finally found a way around it.
We have recently received the exciting news that, with support from the Knut and Alice Wallenberg foundation, Stockholm University, Uppsala University, Lund University, KTH and MaxIV Laboratory, we will be able to initiate a design study of an x-ray laser beamline in Sweden.
Vi har nyligen fått den glädjande och spännande nyheten att, med stöd av Knut och Alice Wallenbergs stiftelse, Stockholms universitet, Uppsala universitet, Lunds universitet, KTH samt MaxIV, kunna initiera en designstudie för en röntgenlaser strålrör i Sverige.
