• "Driving-Induced Symmetry Breaking in the Spin-Boson System", Adam, Winterstetter, Grifoni, Weiss, 1999

  Publication

  A symmetric dissipative two-state system is asymptotically completely delocalized independent of the initial state. We show that driving-induced...

• "Plasmon and charge quantization effects in a double-barrier quantum wire", Braggio, Grifoni, Sassetti, Napoli, 2000

  Publication

  The nonlinear transport properties of a single-channel quantum wire in the presence of two impurities are investigated. Treating the electron...

  Publication

  At small layer separations, the ground state of a ν = 1 bilayer quantum Hall system exhibits spontaneous interlayer phase coherence. The evolution of...
