Fast noise in the Landau-Zener theory RID B-5617-2009
(American Physical Society, 2003)
We study the influence of a fast noise on Landau-Zener transitions. We demonstrate that a fast colored noise much weaker than the conventional white noise can produce transitions itself or can change substantially the ...
Long-wavelength anomalous diffusion mode in the two-dimensional XY dipole magnet
(American Physical Society, 1997)
In a two-dimensional XY ferromagnet the dipole force induces a strong interaction between spin waves in the long-wavelength limit. The major effect of this interaction is the transformation of a propagating spin wave into ...
