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…
Orbital magnetic field effects in spin liquid with spinon Fermi sea: Possible application to -(ET)Cu(CN)
Olexei I. Motrunich
We consider orbital magnetic field effects in a spin liquid phase of a half-filled triangular lattice Hubbard system close to the Mott transition, continuing an earlier exploration…
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…
Criticality in quantum triangular antiferromagnets via fermionized vortices
Jason Alicea, Olexei I. Motrunich, Michael Hermele +1
We revisit two-dimensional frustrated quantum magnetism from a new perspective, with the aim of exploring new critical points and critical phases. We study easy-plane triangular an…
