• "Dissipative dynamics of four-site tunneling of H", Winterstetter, Grifoni, 2000

  Publikation

  We investigate the dissipative properties of a quantum particle which can tunnel among four equivalent sites on a plane. Our four-state system model...

• "Tunneling spectroscopy calculations of a Luttinger wire", Governale, Grifoni, Schön, 2000

  Publikation

  We investigate the tunneling current between a one-dimensional (1D) wave guide and a metallic electrode. To be specific, we consider as an electrode a...

• "Double-occupancy errors, adiabaticity, and entanglement of spin qubits in quantum dots", Schliemann, Loss, MacDonald, 2001

  Publikation

  Quantum gates that temporarily increase singlet-triplet splitting in order to swap electronic spins in coupled quantum dots lead inevitably to a...

• "Strong Correlation to Weak Correlation Phase Transition in Bilayer Quantum Hall Systems", Schliemann, Girvin, MacDonald, 2001

  Publikation

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