• "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...

• "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...

  Publication

  Understanding the interplay between many-body phenomena and nonequilibrium in systems with entangled spin and orbital degrees of freedom is a central...

• "The two classes of low-energy spectra in finite carbon nanotubes", Marganska, Chudzinski, Grifoni, 2015

  Publication

  We study the spectra of finite-length carbon nanotubes (CNTs) of arbitrary chirality. They divide into two classes, which arise because of different...
