Optical charge state control of spin defects in 4H-SiC.
Wolfowicz G, Anderson CP, Yeats AL, Whiteley SJ, Niklas J, Poluektov OG, Heremans FJ, Awschalom DD. Wolfowicz G, et al. Among authors: awschalom dd. Nat Commun. 2017 Nov 30;8(1):1876. doi: 10.1038/s41467-017-01993-4. Nat Commun. 2017. PMID: 29192288 Free PMC article.
Spin qubits exist in specific charge states of these defects, where the ability to control these states can provide enhanced spin-dependent readout and long-term charge stability. We investigate this charge state control for two major spin qubits in 4H-SiC, the divacancy a …

Engineered micro- and nanoscale diamonds as mobile probes for high-resolution sensing in fluid.
Andrich P, Alemán BJ, Lee JC, Ohno K, de las Casas CF, Heremans FJ, Hu EL, Awschalom DD. Andrich P, et al. Among authors: awschalom dd. Nano Lett. 2014 Sep 10;14(9):4959-64. doi: 10.1021/nl501208s. Epub 2014 Aug 4. Nano Lett. 2014. PMID: 25076417
We demonstrate a DC magnetic sensitivity of 9 muT/Hz in fluid as well as long-term trapping stability (>30 h), which paves the way toward the use of high-sensitivity pulse techniques on contactless probes manipulated within biological settings....

Emergence of the persistent spin helix in semiconductor quantum wells.
Koralek JD, Weber CP, Orenstein J, Bernevig BA, Zhang SC, Mack S, Awschalom DD. Koralek JD, et al. Among authors: awschalom dd. Nature. 2009 Apr 2;458(7238):610-3. doi: 10.1038/nature07871. Nature. 2009. PMID: 19340077 Free article.
This symmetry is predicted to be robust against all forms of spin-independent scattering, including electron-electron interactions, but is broken by the cubic Dresselhaus term (beta(3)) and spin-dependent scattering. When these terms are negligible, the distance over which …
