The planar pyrochlore antiferromagnet: A large-N analysis
Jean-Sebastien Bernier, Chung-Hou Chung, Yong Baek Kim +1
We study possible quantum phases of the Heisenberg antiferromagnet on the planar pyrochlore lattice, also known as the checkerboard lattice or the square lattice with crossings. It…
Competing Orders and Superconductivity in the Doped Mott Insulator on the Shastry-Sutherland Lattice
Chung-Hou Chung, Yong Baek Kim
Quantum antiferromagnets on geometrically frustrated lattices often allow a number of unusual paramagnetic ground states. The fate of these Mott insulators upon doping is an import…
Signatures of Electronic Nematic Phase at Isotropic-Nematic Phase Transition
Hae-Young Kee, Eugene H. Kim, Chung-Hou Chung
The electronic nematic phase occurs when the point-group symmetry of the lattice structure is broken, due to electron-electron interactions. We study a model for the nematic phase…
Statistics of spinons in the spin-liquid phase of Cs2CuCl4
Chung-Hou Chung, Klaus Voelker, Yong Baek Kim
Motivated by a recent experiment on Cs2CuCl4, we study the spin dynamics of the spin-liquid phase of the spin-1/2 frustrated Heisenberg antiferromagnet on the anisotropic triangula…
