Pnictides as frustrated quantum antiferromagnet close to a quantum phase transition
Goetz S. Uhrig, Michael Holt, Jaan Oitmaa +2
We present a detailed description of the dynamics of the magnetic modes in the recently discovered superconducting pnictides using reliable self-consistent spin-wave theory and ser…
Why phase diagrams of different underdoped cuprates are remarkably different? Disorder versus bilayer
O. P. Sushkov
Contrary to a widely accepted view the phase diagrams of LaSrCuO and YBaCuO, in spite of similarities are remarkably different. Both the electric…
Spin-stiffness of anisotropic Heisenberg model on square lattice and possible mechanism for pinning of the electronic liquid crystal direction in YBCO
T. Pardini, R. R. P. Singh, A. Katanin +1
Using series expansions and spin-wave theory we calculate the spin-stiffness anisotropy in Heisenberg models on the square lattice with anisotropic couplings $J_x,J…
Diagonal charge modulation in the insulating LaSrCuO
O. P. Sushkov
We show that, due to the Dzyaloshinskii-Moriya and the XY anisotropies, the disordered diagonal spin spiral in the insulating LaSrCuO generates a diagonal charge de…
