"Here, we show that chirality of either handedness can be induced in the nonchiral piezoelectric material boron phosphate..by irradiation with terahertz pulses. Resonant excitation of either one of two orthogonal, degenerate vibrational modes determines the sign of the induced chiral order parameter... Our findings offer new prospects for the control of out-of-equilibrium quantum phenomena in complex materials."

"In this work, we explore the impact of chirality on spin angular momentum in hybrid metal/chiral molecule thin-film heterostructures. For this, we inject a pure spin current via spin pumping and investigate the spin-to-charge conversion at the hybrid chiral interface. Notably, we observe a chiral-induced unidirectionality in the conversion."

Does anyone know if little-endian has any technical advantages? Big-endian machines are all but extinct these days (outside of IBM mainframes).
Or is is just a case of having to pick one and stick with it, like how all life on Earth is made out of L-chiral amino acids and D-chiral carbohydrates?

`Herein we provide a theoretical treatment for this phenomenon, presenting an effective spin-Hamiltonian for helical molecules like DNA and density functional theory (DFT) results on amino acids that confirm the dependence of J-couplings on the choice of enantiomer. The connection between nuclear spin dynamics and #chirality could offer insights for #molecular sensing... These results establish NMR as a potential tool for #chiral discrimination without external agents.`
