• "Dissipative transport in dc-ac–driven tight-binding lattices", Hartmann, Grifoni, Hänggi, 1997

  Publication

  We investigate the incoherent dissipative quantum transport of a particle in a periodic lattice being driven nonlinearly by dc-ac fields. The particle...

• "Coherent and Incoherent Quantum Stochastic Resonance", Grifoni, Hänggi, 1996

  Publication

  We study quantum stochastic resonance (QSR) in the periodically driven biased spin-boson system. The amplitude and the phase of the nonlinear response...

• "Exact master equations for driven dissipative tight-binding models", Grifoni, Sassetti, Weiss, 1996

  Publication

  The dynamics of the driven dissipative two-state system is formulated in terms of an exact nonconvolutive master equation. The kernel is expressed as...

• "Quantum tunneling and stochastic resonance", Grifoni, Hartmann, Berchtold, Hänggi, 1996

  Publication

  Stochastic resonance (SR) occurs in nonlinear dynamical systems when the response to a weak coherent input is enhanced by the presence of noise. While...

• "Simple models suffice for the single-dot quantum shuttle", Donarini, Novotny, Jauho, 2005

  Publication

  A quantum shuttle is an archetypical nanoelectromechanical device, where the mechanical degree of freedom is quantized. Using a full-scale numerical...
