Quadrupolar correlations and spin freezing in S = 1 triangular lattice antiferromagnets
E. M. Stoudenmire, Simon Trebst, Leon Balents
Motivated by experiments on NiGa2S4, we discuss characteristic (finite temperature) properties of spin S = 1 quantum antiferromagnets on the triangular lattice. Several recent theo…
A Spin-Orbital Singlet and Quantum Critical Point on the Diamond Lattice: FeSc2S4
Gang Chen, Leon Balents, Andreas P. Schnyder
We present a theory of spin and orbital physics in the A-site spinel compound FeSc2S4, which experimentally exhibits a broad "spin-orbital liquid" regime. A spin-orbital Hamiltonia…
Supersolid Order of Frustrated Hard-Core Bosons in a Triangular Lattice System
H. C. Jiang, M. Q. Weng, Z. Y. Weng +2
We numerically demonstrate that a supersolid phase exists in a frustrated hard-core boson system on a triangular lattice over a wide range of interaction strength. In the infinite…
Gapless spin liquids on the three dimensional hyper-kagome lattice of NaIrO
Michael Lawler, Arun Paramekanti, Yong Baek Kim +1
Recent experiments indicate that NaIrO, a material in which s=1/2 iridium local moments form a three dimensional network of corner-sharing triangles, may have a quantum…
Ordered Phases of the Anisotropic Kagome Lattice Antiferromagnet in a Field
E. M. Stoudenmire, Leon Balents
The antiferromagnetic Heisenberg model on an anisotropic kagome lattice may be a good minimal model for real magnetic systems as well as a limit from which the isotropic case can b…
Spinons and triplons in spatially anisotropic frustrated antiferromagnets
Masanori Kohno, Oleg A. Starykh, Leon Balents
The search for elementary excitations with fractional quantum numbers is a central challenge in modern condensed matter physics. We explore the possibility in a realistic model for…
