• "Nonadiabatic Quantum Brownian Rectifiers", Goychuk, Grifoni, Hänggi, 1998

  Publication

  We study both dissipative and nondissipative quantum transport in discrete Brownian rectifiers being driven by nonthermal noise that is unbiased on...

• "Comment on “Transient dynamics of Ohmic dissipative two-level systems driven by dc-ac fields” by Wang and Zhao", Grifoni, Hartmann, Hänggi, 1997

  Publication

  Recent results on the dynamics of a two-state system driven by dc-ac fields are discussed. We show that the approximation put forward in the work by...
