Anisotropic pyrochlores and the global phase diagram of the checkerboard antiferromagnet
Oleg A. Starykh, Akira Furusaki, Leon Balents
We study the phase diagram of two models of spin-1/2 antiferromagnets composed of corner-sharing tetrahedra, the basis of the pyrochlore structure. Primarily, we focus on the Heise…
Bond order from disorder in the planar pyrochlore magnet
O. Tchernyshyov, O. A. Starykh, R. Moessner +1
We study magnetic order in the Heisenberg antiferromagnet on the checkerboard lattice, a two-dimensional version of the pyrochlore network with strong geometric frustration. By emp…
Comment on "Critical spin dynamics of the 2D quantum Heisenberg antiferromagnets: Sr2CuO2Cl2 and Sr2Cu3O4Cl2"
Subir Sachdev, Oleg A. Starykh
We compare the neutron measurements of Kim et al. (cond-mat/0012239) on two-dimensional, S=1/2 antiferromagnets with the continuum quasiclassical theory of S. Sachdev and O.A. Star…
Gapped Phases of Quantum Wires
O. A. Starykh, D. L. Maslov, W. Häusler +1
We investigate possible nontrivial phases of a two-subband quantum wire. It is found that inter- and intra-subband interactions may drive the electron system of the wire into a gap…
Thermally fluctuating superconductors in two dimensions
Subir Sachdev, Oleg A. Starykh
We describe the different regimes of finite temperature dynamics in the vicinity of a zero temperature superconductor to insulator quantum phase transition in two dimensions. New r…
On the behavior of a Heisenberg antiferromagnet at very low temperatures
Andrey V. Chubukov, Oleg A. Starykh
We present an analytical result for the ratio of the physical correlation length in a 2D Heisenberg antiferromagnet on a square lattice, and the one which is actually computed in n…
