Physicists at MIT have observed direct evidence of unconventional superconductivity in magic-angle twisted tri-layer graphene, revealing a distinctive V-shaped energy gap. This breakthrough suggests electron pairing driven by strong interactions rather than lattice vibrations. The findings, published in Science, could pave the way for room-temperature superconductors.

Researchers at TU Wien have discovered that electrons escaping from solid materials require specific 'doorway states' beyond just sufficient energy, resolving long-standing experimental anomalies. This finding, published in Physical Review Letters, explains variations in electron emission from layered materials like graphene. The insight opens new possibilities for engineering advanced materials.
