Crystal structure and temperature dependence of resistivity of EIO/DTO. Credit: Science Advances (2025). DOI: 10.1126/sciadv.adr6202 Scientists have discovered a new way that matter can exist—one that is different from the usual states of solid, liquid, gas or plasma—at the interface of two exotic materials made into a sandwich. The new quantum state, called quantum liquid crystal, appears to follow its own rules and offers characteristics that could pave the way for advanced technological appli...
