Theory of Anisotropic Hopping Transport due to Spiral Correlations in the Spin-Glass Phase of Underdoped Cuprates
Valeri N. Kotov, Oleg P. Sushkov
We study the in-plane resistivity anisotropy in the spin-glass phase of the high- cuprates, on the basis of holes moving in a spiral spin background. This picture follows fr…
The Magnetism of Li doped LaCuO: the antiferromagnetic spin-shard state
O. P. Sushkov, A. H. Castro Neto
We study the dynamics of a single hole in Li and Sr doped LaCuO and its extension to a finite hole concentration. We compare the physics of LaSrCuO and La…
Bose-Einstein condensation of magnons in TlCuCl
J. Sirker, A. Weisse, O. P. Sushkov
A quantitative study of the field-induced magnetic ordering in TlCuCl in terms of a Bose-Einstein condensation (BEC) of magnons is presented. It is shown that the hitherto prop…
Consequences of spin-orbit coupling for the Bose-Einstein condensation of magnons
J. Sirker, A. Weiße, O. P. Sushkov
In the first part we discuss how the BEC picture for magnons is modified by anisotropies induced by spin-orbit coupling. In particular we focus on the effects of antisymmetric spin…
Conductance structure in a one-dimensional quantum contact: dependence on the longitudinal magnetic field
O. P. Sushkov
Very short quantum wires (quantum contacts) exhibit a conductance structure at the value of conductance close to 0.7 x 2e^2/h. The structure was discovered by Thomas et al (Phys. R…
Spin stripe dimerization in the t-J model
O . P. Sushkov
In the present work we demonstrate that the spin columnar dimerized phase (conducting spin stripe liquid) is stable at doping . At the system unde…
