We investigate combined effects of spin-orbit coupling and magnetic field in carbon nanotubes containing one or more bends along their length. We show how bends can be used to provide electrical control of confined spins, while spins confined in straight segments remain insensitive to electric fields. Device geometries that allow general rotation of single spins are presented and analyzed. In addition, capacitive coupling along bends provides coherent spin-spin interaction, including between… Expand

Electrical control of strong spin-phonon coupling in a carbon nanotube
TLDR
Numerical simulations with experimentally reachable parameters show that high fidelity quantum state transfer between mechanical and spin qubits driven by electrical pulses is feasible and forms the basis for the fully electrical control of the coherent interconvertion between light andspin qubits.

Photo-spintronics of spin-orbit active electric weak links
We show that a carbon nanotube can serve as a functional electric weak link performing photo-spintronic transduction. A spin current, facilitated by strong spin-orbit interactions in the nanotube andExpand
Noncollinear Spin-Orbit Magnetic Fields in a Carbon Nanotube Double Quantum Dot.
TLDR
It is demonstrated experimentally that noncollinear intrinsic spin-orbit magnetic fields can be realized in a curved carbon nanotube two-segment device and the four unique spin directions of the quantum states for specific shells and magnetic fields are determined. Expand
Carbon nanotubes in electric and magnetic fields
We derive an effective low-energy theory for metallic (armchair and non-armchair) single-wall nanotubes in the presence of an electric field perpendicular to the nanotube axis, and in the presence ofExpand
Switchable Coupling of Vibrations to Two-Electron Carbon-Nanotube Quantum Dot States.
TLDR
The magnetic-field dependence indicates that only the two-electron spin-triplet excited state couples to the mechanical motion, indicating mechanical coupling to both the valley degree of freedom and the exchange interaction, in contrast to standard models. Expand

TLDR
It is demonstrated that the fractional resonances-counterparts of multiphoton transitions for atoms in strong laser fields-occurring in electrically controlled nanodevices already at moderate ac amplitudes-can be used to maintain the spin-flip transitions. Expand
Readout of carbon nanotube vibrations based on spin-phonon coupling
We propose a scheme for spin-based detection of the bending motion in suspended carbon-nanotubes, using the curvature-induced spin-orbit interaction. We show that the resulting effective spin-phononExpand
Large spin-orbit coupling in carbon nanotubes.
TLDR
A spin-orbit coupling in three carbon nanotube devices that is an order of magnitude larger than previously measured is reported, and its strength is promising for applications of the spin- orbit interaction in carbon Nanotubes devices. Expand
Rashba spin-splitting of single electrons and Cooper pairs
Electric weak links, the term used for those parts of an electrical circuit that provide most of the resistance against the flow of an electrical current, are important elements of many nanodevices.Expand
Gate-dependent spin-orbit coupling in multielectron carbon nanotubes
The coupling of spin and orbital motion of electrons in carbon nanotubes has been demonstrated before, but a study now shows that the strength and sign of the spin–orbit coupling can be tuned by aExpand
