Production, storage and release of spin currents in quantum circuits
Michele Cini
Quantum rings connected to ballistic circuits couple strongly to external magnetic fields if the connection is not symmetric. By analytical theory and computer simulation I show th…
Quantum Rings in Magnetic Fields and Spin Current Generation
Michele Cini, Stefano Bellucci
We propose three different mechanisms for pumping spin-polarized currents in a ballistic circuit using a time-dependent magnetic field acting on an asymmetrically connected quantum…
Magnetically induced pumping and memory storage in quantum rings
Michele Cini, Enrico Perfetto
Nanoscopic rings pierced by external magnetic fields and asymmetrically connected to wires behave in sharp contrast with classical expectations. By studying the real-time evolution…
Advances in nonequilibrium transport with long-range interactions
E. Perfetto, G. Stefanucci, M. Cini
The effects of long-range interactions in quantum transport are still largely unexplored, mainly due to the difficulty of devising efficient embedding schemes. In this work we pres…
Correlation induced memory effects in the transport properties of low dimensional systems
E. Perfetto, G. Stefanucci, M. Cini
We demonstrate the remnant presence of {\em initial} correlations in the {\em steady-state} electrical current flowing between low-dimensional interacting leads. The leads are desc…
Time-dependent transport in graphene nanoribbons
E. Perfetto, G. Stefanucci, M. Cini
We theoretically investigate the time-dependent ballistic transport in metallic graphene nanoribbons after the sudden switch-on of a bias voltage . The ribbon is divided in thre…
