    • Fast noise in the Landau-Zener theory RID B-5617-2009 
      Pokrovsky, Valery L.; Sinitsyn, NA. (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 ...
    • Landau-Zener transitions in a linear chain 
      Pokrovsky, Valery L.; Sinitsyn, NA. (American Physical Society, 2002)
      We present an exact asymptotic solution for electron transition amplitudes in an infinite linear chain driven by an external time-dependent electric field. This solution extends the Landau-Zener theory for the case of an ...
    • Spin transitions in time-dependent regular and random magnetic fields 
      Pokrovsky, Valery L.; Sinitsyn, NA. (American Physical Society, 2004)
      We study the transition between Zeeman levels of an arbitrary spin placed into a regular time-dependent magnetic field and a random field with the Gaussian distribution. One component of the regular field changes its sign ...
