Fate of partial order on the trillium and distorted windmill lattices
Sergei V. Isakov, John M. Hopkinson, Hae-Young Kee
The classical Heisenberg model on the trillium and distorted windmill lattices exhibits a degenerate ground state within large- theory, where the degenerate wavevectors form a s…
Spin Triplet Excitations for a Valence Bond Solid on the Kagome Lattice
Bohm-Jung Yang, Yong Baek Kim, Jaejun Yu +1
One of the most promising candidate ground states for the quantum antiferromagnetic Heisenberg model on the Kagome lattice is the valence bond solid (VBS) with a 36-site unit cell.…
Intimate relations between electronic nematic, d-density wave and d-wave superconducting states
Hae-Young Kee, Hyeonjin Doh, Thomas Grzesiak
This paper consists of two important theoretical observations on the interplay between l = 2 condensates; d-density wave (ddw), electronic nematic and d-wave superconducting states…
Exotic phase diagram of a cluster charging model of bosons on the kagome lattice
Sergei V. Isakov, Arun Paramekanti, Yong Baek Kim
We study a model of hard-core bosons on the kagome lattice with short-range hopping () and repulsive interactions (). This model directly maps on to an easy-axis XXZ…
