Theory Briefing
- Chirality-Induced Spin Selectivity (CISS) describes how helical molecules preferentially transmit electrons of one spin orientation, a phenomenon still lacking a unified theory.
- Researchers are building a first-principles framework to quantitatively predict CISS behavior, bridging quantum mechanics and real-world materials design.
- A robust predictive model for CISS could revolutionize spintronics and even explain spin-selective processes in biological molecules like DNA.
