Résumé

We introduce an unfamiliar Kondo ladder problem by coupling the well-known Takhtajan-Babujan S=1chain to a half-filled one-dimensional electron gas, and we solve it using quantum field theory techniques. Based on the so-called underscreened Kondo effect, we find an insulating spin liquid with both deconfined spinons and optical magnons. Important consequences are discussed.
