Carbyne from first principles: Chain of C atoms, a nanorod or a nanorope?
• ARXIV.OrgWe investigate carbyne's mechanical response to tension, bending, and torsion deformations. Under tension, carbyne is about twice as stiff as the stiffest known materials and has an unrivaled specific strength of up to 7.5*10^{7} Nm/kg, requiring a f
