Quantum Impurity Model Reveals Pairing, Pseudogap, And Phase Transitions At, Favoring Singlet Or Valley Doublet Configurations

09 Nov 2025 | Category: Science

Researchers have discovered that interactions between electrons in a specially constructed material create unusual quantum states, exhibiting properties like enhanced pairing and distinct phase transitions even at the level of individual atomic imperfections.

The peculiar behaviour of electrons in twisted, layered materials, known as moiré systems, continues to challenge our understanding of quantum physics, and recent studies suggest a surprising co-existence of both heavy and light electrons within thes...
