An international team of researchers, including some from the University of Bonn, has demonstrated an exotic quantum state of matter
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.”
