Negative differential conductance in quantum dots in theory and experiment
M. C. Rogge, F. Cavaliere, M. Sassetti +2
Experimental results for sequential transport through a lateral quantum dot in the regime of spin blockade induced by spin dependent tunneling are compared with theoretical results…
Dynamics of a domain wall and spin-wave excitations driven by a mesoscopic current
Jun-ichiro Ohe, Bernhard Kramer
The dynamics of a domain wall driven by a spin-polarized current in a mesoscopic system is studied numerically. Spin-mixing in the states of the conduction electrons is fully taken…
Spin polarization in a T-shape conductor induced by strong Rashba spin-orbit coupling
M. Yamamoto, T. Ohtsuki, B. Kramer
We investigate numerically the spin polarization of the current in the presence of Rashba spin-orbit interaction in a T-shaped conductor proposed by A.A. Kiselev and K.W. Kim (Appl…
Electron correlations and single-particle physics in the Integer Quantum Hall Effect
Alexander Struck, Bernhard Kramer
The compressibility of a two-dimensional electron system with spin in a spatially correlated random potential and a quantizing magnetic field is investigated. Electron-electron int…
Nonchiral Edge States at the Chiral Metal Insulator Transition in Disordered Quantum Hall Wires
Alexander Struck, Bernhard Kramer, Tomi Ohtsuki +1
The quantum phase diagram of disordered wires in a strong magnetic field is studied as a function of wire width and energy. The two-terminal conductance shows zero-temperature disc…
