Explaining the magnitude of Chirality-Induced Spin Selectivity via electron-electron exchange
Summary
arXiv:2607.06858v1 Announce Type: new Abstract: Chiral molecular structure can couple to electron spin, leading to unexpected spin polarization effects. This Chirality-Induced Spin Selectivity (CISS) was first reported for DNA molecules adsorbed on gold but its microscopic origin remains unclear. We demonstrated though simulation that the exchange arising from electron-electron Coulomb interactions within the self-consistent mean field (Hartree--Fock) approximation can yield significant ($\sim 2\%$) spin polarisation for $3$-methylcyclohexanone adsorbed on Cu(111) amplifying a much smaller ($\sim 0.0014\%$) initial bias, consistent with experiment.
Why It Matters
This Quantum development moves quantum capability closer to commercial and national-security relevance. For Asia, it is a signal worth tracking: it shapes who supplies, who scales, and who sets the standard over the next five years.
