Nanomechanical Detection of Itinerant Electron Spin Flip
Guiti Zolfagharkhani, Alexei Gaidarzhy, Pascal Degiovanni +3
Spin is an intrinsically quantum property, characterized by angular momentum. A change in the spin state is equivalent to a change in the angular momentum or mechanical torque. Thi…
Conductance plateau transitions in quantum Hall wires with spatially correlated random magnetic fields
Tohru Kawarabayashi, Yoshiyuki Ono, Tomi Ohtsuki +3
Quantum transport properties in quantum Hall wires in the presence of spatially correlated disordered magnetic fields are investigated numerically. It is found that the correlation…
Coherent laser control of the current through molecular junctions
Guangqi Li, Michael Schreiber, Ulrich Kleinekathoefer
The electron tunneling through a molecular junction modeled by a single site weakly coupled to two leads is studied in the presence of a time-dependent external field using a maste…
Unconventional conductance plateau transitions in quantum Hall wires with spatially correlated disorder
Tohru Kawarabayashi, Yoshiyuki Ono, Tomi Ohtsuki +3
Quantum transport properties in quantum Hall wires in the presence of spatially correlated random potential are investigated numerically. It is found that the potential correlation…
Mesoscopic Hall effect driven by chiral spin order
Jun-ichiro Ohe, Tomi Ohtsuki, Bernhard Kramer
A Hall effect due to spin chirality in mesoscopic systems is predicted. We consider a 4-terminal Hall system including local spins with geometry of a vortex domain wall, where stro…
