    • Coherence of nitrogen-vacancy electronic spin ensembles in diamond 

      Stanwix, P. L.; Pham, L. M.; Maze, Jeronimo R.; Le Sage, David; Yeung, T. K.; e.a. (American Physical Society, 2010-11)
      We present an experimental and theoretical study of electronic spin decoherence in ensembles of nitrogen-vacancy (NV) color centers in bulk high-purity diamond at room temperature. Under appropriate conditions, we find ...
    • Enhanced solid-state multispin metrology using dynamical decoupling 

      Cappellaro, Paola; Pham, L. M.; Bar-Gill, N.; Belthangady, C.; Sage, D. Le; e.a. (American Physical Society, 2012-07)
      We use multipulse dynamical decoupling to increase the coherence lifetime (T[subscript 2]) of large numbers of nitrogen-vacancy (NV) electronic spins in room temperature diamond, thus enabling scalable applications of ...
    • Fourier magnetic imaging with nanoscale resolution and compressed sensing speed-up using electronic spins in diamond 

      Belthangady, C.; Zhang, H.; Bar-Gill, N.; DeVience, S. J.; Yacoby, A.; e.a. (Nature Publishing Group, 2015-08)
      Optically detected magnetic resonance using nitrogen–vacancy (NV) colour centres in diamond is a leading modality for nanoscale magnetic field imaging, as it provides single electron spin sensitivity, three-dimensional ...
    • Logarithmic singularities and quantum oscillations in magnetically doped topological insulators 

      Nandi, D.; Shain, K.; Lee, G. H.; Huang, K.-F.; Chang, Cui-Zu; e.a. (American Physical Society, 2018-02)
      We report magnetotransport measurements on magnetically doped (Bi,Sb)[subscript 2]Te[subscript 3] films grown by molecular beam epitaxy. In Hall bar devices, we observe logarithmic dependence of transport coefficients in ...
    • Magnetic field imaging with nitrogen-vacancy ensembles 

      Pham, L. M.; Le Sage, David; Stanwix, P. L.; Yeung, T. K.; Glenn, David; e.a. (Institute of Physics, 2011-04)
      Part of Focus on Diamond-Based Photonics and Spintronics We demonstrate a method of imaging spatially varying magnetic fields using a thin layer of nitrogen-vacancy (NV) centers at the surface of a diamond chip. ...
    • Magnetostatic twists in room-temperature skyrmions explored by nitrogen-vacancy center spin texture reconstruction 

      Casola, F.; Zhou, T. X.; Büttner, F.; Walsworth, R. L.; Yacoby, A.; e.a. (Nature Publishing Group, 2018-07)
      Magnetic skyrmions are two-dimensional non-collinear spin textures characterized by an integer topological number. Room-temperature skyrmions were recently found in magnetic multilayer stacks, where their stability was ...
    • Nanoscale magnetic sensing using spin qubits in diamond 

      Maze, Jeronimo R.; Cappellaro, Paola; Childress, L.; Dutt, M. V. G.; Hodges, Jonathan S.; e.a. (Society of Photo-optical Instrumentation Engineers, 2009-02)
      The ability to sense nanotelsa magnetic fields with nanoscale spatial resolution is an outstanding technical challenge relevant to the physical and biological sciences. For example, detection of such weak localized fields ...
    • Signatures of long-range-correlated disorder in the magnetotransport of ultrathin topological insulators 

      Lee, G. H.; Huang, K.-F.; Shain, K.; Lee, S.-P.; Ward, J.; e.a. (American Physical Society, 2018-12)
      In an ultrathin topological insulator (TI) film, a hybridization gap opens in the TI surface states, and the system is expected to become either a trivial insulator or a quantum spin Hall insulator when the chemical potential ...
    • Spatially resolved edge currents and guided-wave electronic states in graphene 

      Allen, M. T.; Fulga, I. C.; Akhmerov, A. R.; Watanabe, K.; Taniguchi, T.; e.a. (Nature Publishing Group, 2015-11)
      Exploiting the light-like properties of carriers in graphene could allow extreme non-classical forms of electronic transport to be realized. In this vein, finding ways to confine and direct electronic waves through nanoscale ...
    • Suppression of spin-bath dynamics for improved coherence of multi-spin-qubit systems 

      Bar-Gill, N.; Pham, L.M.; Belthangady, C.; Le Sage, David; Maze, Jeronimo R.; e.a. (Nature Publishing Group, 2012-05)
      Multi-qubit systems are crucial for the advancement and application of quantum science. Such systems require maintaining long coherence times while increasing the number of qubits available for coherent manipulation. For ...
