How can a structure hold together if its individual components are actually repelling one another? An international research team has now demonstrated one example of such a highly excited exotic quantum state of matter. Researchers from the University of Bonn played a major role in the study. The findings have now been published in the journal "Nature."

Atoms consist of a positively charged nucleus and a number of negatively charged electrons. They form a stable object since the nucleus and the electrons attract each other. ...
