摘要

The speed at which a jet can travel or a centrifuge can spin is limited by rotor disintegration. As the turbine of a jet or the rotor of a centrifuge goes round, it experiences a centrifugal force, which increases in proportion to the square of its rotational velocity. As the rotor speeds up there is some point beyond which the mechanical strength of the rotor cannot withstand the centrifugal force and the rotor breaks. In two papers in Physical Review Letters, Corkum and co-workers demonstrate that rotor disintegration will also happen to individual molecules if they are made to spin rapidly enough.
