Local optical control of ferromagnetism and chemical potential in a topological insulator
Andrew L. Yeats, Peter J. Mintun, Yu Pan +4
Many proposed experiments involving topological insulators (TIs) require spatial control over time-reversal symmetry and chemical potential. We demonstrate reconfigurable micron-sc…
First-principles theory of the luminescence lineshape for the triplet transition in diamond NV centre
Audrius Alkauskas, Bob B. Buckley, David D. Awschalom +1
In this work we present theoretical calculations and analysis of the vibronic structure of the spin-triplet optical transition in diamond nitrogen-vacancy centres. The electronic s…
Electrically and mechanically tunable electron spins in silicon carbide color centers
Abram L. Falk, Paul V. Klimov, Bob B. Buckley +6
The electron spins of semiconductor defects can have complex interactions with their host, particularly in polar materials like SiC where electrical and mechanical variables are in…
Electrically driven spin resonance in silicon carbide color centers
P. V. Klimov, A. L. Falk, B. B. Buckley +1
We demonstrate that the spin of optically addressable point defects can be coherently driven with AC electric fields. Based on magnetic-dipole forbidden spin transitions, this sche…
Polytype control of spin qubits in silicon carbide
Abram L. Falk, Bob B. Buckley, Greg Calusine +6
Crystal defects can confine isolated electronic spins and are promising candidates for solid-state quantum information. Alongside research focusing on nitrogen vacancy centers in d…
Measurement and Control of Single Nitrogen-Vacancy Center Spins above 600 K
D. M. Toyli, D. J. Christle, A. Alkauskas +3
We study the spin and orbital dynamics of single nitrogen-vacancy (NV) centers in diamond between room temperature and 700 K. We find that the ability to optically address and cohe…
Electrical Tuning of Single Nitrogen-Vacancy Center Optical Transitions Enhanced by Photoinduced Fields
L. C. Bassett, F. J. Heremans, C. G. Yale +2
We demonstrate precise control over the zero-phonon optical transition energies of individual nitrogen-vacancy (NV) centers in diamond by applying multiaxis electric fields, via th…
High cooperativity coupling of electron-spin ensembles to superconducting cavities
D. I. Schuster, A. P. Sears, E. Ginossar +6
Electron spins in solids are promising candidates for quantum memories for superconducting qubits because they can have long coherence times, large collective couplings, and many q…
