Research reveals that a quantum ‘umbilical cord’ connects the metal and insulator states of many materials
DFT+DMFT calculations for copper oxide waterfalls. Credit: Nature Communications (2025). DOI: 10.1038/s41467-024-55465-7 Some materials exhibit a kind of umbilical cord between different quantum states. Researchers at the Vienna University of Technology have shown that this “umbilical cord” is common to many materials. This is the basic principle of quantum theory. Certain physical quantities may only assume very specific values. All…
