Tang et al. discovered neutronic molecules, in which neutrons can be made to cling to quantum dots, held just by the strong force: the red item represents a bound neutron, the sphere is a hydride nanoparticle, and the yellow field represents a neutron wavefunction.

Scientists Discover ‘Neutronic Molecules’

Neutrons are subatomic particles that have no electric charge, unlike protons and electrons. That means that while the electromagnetic force is responsible...

An electron is trapped in a quantum dot, which is formed in a 2D gas in a semiconductor wafer. However, the electron moves within the space and, with different probabilities corresponding to a wave function, remains in certain locations within its confinement (red ellipses). Using the gold gates applied electric fields, the geometry of this wave function can be changed. Image credit: University of Basel.
