Studies of non-magnetic impurities in the spin-1/2 Kagome Antiferromagnet
Karol Gregor, Olexei I. Motrunich
Motivated by recent experiments on ZnCu(OH)Cl, we study the inhomogeneous Knight shifts (local susceptibilities) of spin 1/2 Kagome antiferromagnet in the presence of n…

Spin solid phases of spin 1 and spin 3/2 antiferromagnets on a cubic lattice
Karol Gregor, Olexei I. Motrunich
We study spin S=1 and S=3/2 Heisenberg antiferromagnets on a cubic lattice focusing on spin solid states. Using Schwinger boson formulation for spins, we start in a U(1) spin liqui…

Spin-nematic order in the frustrated pyrochlore-lattice quantum rotor model
Karol Gregor, David A. Huse, S. L. Sondhi
As an example of ordering due to quantum fluctuations, we examine the nearest-neighbor antiferromagnetic quantum O(n) rotor model on the pyrochlore lattice. Classically, this syste…
