Numerically Exact Configuration Interaction at Quadrillion-Determinant Scale
Agam Shayit, Can Liao, Shiv Upadhyay +5
The combinatorial scaling of configuration interaction (CI) has long restricted its applicability to only the simplest molecular systems. Here, we report the first numerically exac…

Chirality-Driven Magnetization Emerges from Relativistic Four-Current Dynamics
Shiv Upadhyay, Xuechen Zheng, Tian Wang +4
Chirality-induced spin selectivity (CISS) is a striking quantum phenomenon in which electron transport through chiral molecules leads to spin polarization -- even in the absence of…
