Emergent Potts order in the kagomé $J_1-J_3$ Heisenberg model

Vincent Grison, Pascal Viot, Bernard Bernu +1

Motivated by the physical properties of Vesignieite BaCu${}_3$V${}_2$O${}_8$(OH)${}_2$, we study the $J_1-J_3$ Heisenberg model on the kagomé lattice, that is proposed to describe this com…
