Side-jumps in the spin-Hall effect: construction of the Boltzmann collision integral
Dimitrie Culcer, E. M. Hankiewicz, Giovanni Vignale +1
We present a systematic derivation of the side-jump contribution to the spin-Hall current in systems without band structure spin-orbit interactions, focusing on the construction of…
Steady-state spin densities and currents
Dimitrie Culcer
This article reviews steady-state spin densities and spin currents in materials with strong spin-orbit interactions. These phenomena are intimately related to spin precession due t…
Dephasing of Si spin qubits due to charge noise
Dimitrie Culcer, Xuedong Hu, S. Das Sarma
Spin qubits in Silicon quantum dots can have long coherence times, yet their manipulation relies on the exchange interaction, through which charge noise can induce decoherence. Cha…
Exchange coupling in silicon quantum dots: Theoretical considerations for quantum computation
Qiuzi Li, Lukasz Cywinski, Dimitrie Culcer +2
We study exchange coupling in Si double quantum dots, which have been proposed as suitable candidates for spin qubits due to their long spin coherence times. We discuss in detail t…
Semiclassical spin transport in spin-orbit-coupled systems
Dimitrie Culcer
This article discusses spin transport in systems with spin-orbit interactions and how it can be understood in a semiclassical picture. I will first present a semiclassical wave-pac…
Realizing singlet-triplet qubits in multivalley Si quantum dots
Dimitrie Culcer, Lukasz Cywinski, Qiuzi Li +2
There has been significant progress in the implementation and manipulation of singlet-triplet qubits in GaAs quantum dots. Given the considerably longer spin coherence times measur…
