With seven protons and two neutrons, the lopsided atomic nucleus of nitrogen-9 pushes the limits of what can even be considered a nucleus.
pushes the limits of what can even be considered a nucleus at all. Yet signs of its existence seem to be lurking in years-old data from experiments seeking out a different unusual nucleus, researchers report in the Oct. 27If follow-up studies can confirm the detection, nitrogen-9 will be the first nucleus spotted with five more protons than it can stably hold — until now, the limit was four.
Beyond this overflow point, which physicists call the “drip line,” nuclei cannot fully bind their particles. Finding a nucleus as far beyond the drip line as nitrogen-9 — five protons beyond — was surprising even for Charity’s team. Until now, scientists had only ever found isotopes up to four protons beyond the drip line.

Interacting polarons: Physicists simulate interacting quasiparticles in ultracold quantum gasAn electron moving through a solid generates a polarization in its environment due to its electric charge. In his theoretical considerations, the Russian physicist Lev Landau extended the description of such particles by their interaction with the environment and spoke of quasiparticles.

Physicists simulate interacting quasiparticles in ultracold quantum gasIn physics, quasiparticles are used to describe complex processes in solids. In ultracold quantum gases, these quasiparticles can be reproduced and studied. Now scientists have been able to observe in experiments how Fermi polarons -- a special type of quasiparticle -- can interact with each other.
