Tacticity in chiral phononic crystals

HIGHLIGHTS

• who: A. Bergamini from the Laboratory have published the article: Tacticity in chiral phononic crystals, in the Journal: NATURE COMMUNICATIONS NATURE COMMUNICATIONS
• what: The authors show that, beyond the exploitation of inertial effects, the relative orientation of adjacent chiral centers, known from polymer science as tacticity, strongly affects the nature of the coupling between the spins of atoms in the chain. The enriched kinematics makes the work distinct from previous studies, as the frequency shift is solely due to the spin introduction and not to any stiffness or mass changes of the unit cell19,39 . . .
