Diagnosing Deconfinement and Topological Order
K. Gregor, David A. Huse, R. Moessner +1
Topological or deconfined phases are characterized by emergent, weakly fluctuating, gauge fields. In condensed matter settings they inevitably come coupled to excitations that carr…
Impurities in triangular lattice spin 1/2 antiferromagnet
Karol Gregor, Olexei I. Motrunich
We study effects of nonmagnetic impurities in a spin-1/2 frustrated triangular antiferromagnet with the aim of understanding the observed broadening of C NMR lines in the or…
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…
Dipolar spin correlations in classical pyrochlore magnets
S. V. Isakov, K. Gregor, R. Moessner +1
We study spin correlations for the highly frustrated classical pyrochlore lattice antiferromagnets with O(N) symmetry in the limit T->0. We conjecture that a local constraint obeye…
