Gapless spin-liquid phase in the kagome spin-1/2 Heisenberg antiferromagnet
Yasir Iqbal, Federico Becca, Sandro Sorella +1
We study the energy and the static spin structure factor of the ground state of the spin-1/2 quantum Heisenberg antiferromagnetic model on the kagome lattice. By the iterative appl…

Valence-bond crystals in the kagome spin-1/2 Heisenberg antiferromagnet: a symmetry classification and projected wave function study
Yasir Iqbal, Federico Becca, Didier Poilblanc
In this paper, we do a complete classification of valence-bond crystals (VBCs) on the kagome lattice based on general arguments of symmetry only and thus identify many new VBCs for…
