Photovoltaic effect in bent quantum wires
Yu. V. Pershin, C. Piermarocchi
We propose a scheme for the generation of photocurrent in bent quantum wires. We calculate the current using a generalized Landauer-Buttiker approach that takes into account the el…
Spin-photovoltaic effect in quantum wires due to inter-subband transitions
A. Fedorov, Yu. V. Pershin, C. Piermarocchi
We consider the current induced in a quantum wire by external electromagnetic radiation. The photocurrent is caused by the interplay of spin-orbit interaction (Rashba and Dresselha…
Persistent and radiation-induced currents in distorted quantum rings
Yuriy V. Pershin, Carlo Piermarocchi
Persistent and radiation-induced currents in distorted narrow quantum rings are theoretically investigated. We show that ring distorsions can be described using a geometrical poten…
Spin Photovoltaic Effect in Quantum Wires with Rashba Interaction
Yuriy V. Pershin, Carlo Piermarocchi
We propose a mechanism for spin polarized photocurrent generation in quantum wires. The effect is due to the combined effect of Rashba spin-orbit interaction, external magnetic fie…
Laser-controlled local magnetic field with semiconductor quantum rings
Yuriy V Pershin, Carlo Piermarocchi
We analize theoretically the dynamics of N electrons localized in a semiconductor quantum ring under a train of phase-locked infrared laser pulses. The pulse sequence is designed t…
Experimental realization of the one qubit Deutsch-Jozsa algorithm in a quantum dot
P. Bianucci, A. Muller, C. K. Shih +3
We perform quantum interference experiments on a single self-assembled semiconductor quantum dot. The presence or absence of a single exciton in the dot provides a qubit that we co…
