Quantum stabilization of 1/3-magnetization plateau in Cs_2CuBr_4
Jason Alicea, Andrey V. Chubukov, Oleg A. Starykh
We consider the phase diagram of a spatially anisotropic 2D triangular antiferromagnet in a magnetic field. Classically, the ground state is umbrella-like for all fields, but we sh…
Monopole Quantum Numbers in the Staggered Flux Spin Liquid
Jason Alicea
Algebraic spin liquids, which are exotic gapless spin states preserving all microscopic symmetries, have been widely studied due to potential realizations in frustrated quantum mag…
Algebraic vortex liquid theory of a quantum antiferromagnet on the kagome lattice
S. Ryu, O. I. Motrunich, J. Alicea +1
There is growing evidence from both experiment and numerical studies that low half-odd integer quantum spins on a kagome lattice with predominant antiferromagnetic near neighbor in…
Order by disorder and spiral spin liquid in frustrated diamond lattice antiferromagnets
Doron Bergman, Jason Alicea, Emanuel Gull +2
Frustration refers to competition between different interactions that cannot be simultaneously satisfied, a familiar feature in many magnetic solids. Strong frustration results in…
Theory of the algebraic vortex liquid in an anisotropic spin-1/2 triangular antiferromagnet
Jason Alicea, Olexei I. Motrunich, Matthew P. A. Fisher
We explore spin-1/2 triangular antiferromagnets with both easy-plane and lattice exchange anisotropies by employing a dual vortex mapping followed by a fermionization of the vortic…
Algebraic vortex liquid in spin-1/2 triangular antiferromagnets: Scenario for Cs_2CuCl_4
Jason Alicea, Olexei I. Motrunich, Matthew P. A. Fisher
Motivated by inelastic neutron scattering data on Cs_2CuCl_4, we explore spin-1/2 triangular lattice antiferromagnets with both spatial and easy-plane exchange anisotropies, the la…
