    • Control and local measurement of the spin chemical potential in a magnetic insulator 

      Du, Chunhui; van der Sar, Toeno; Zhou, Tony X.; Upadhyaya, Pramey; Casola, Francesco; e.a. (American Association for the Advancement of Science (AAAS), 2017-07)
      The spin chemical potential characterizes the tendency of spins to diffuse. Probing this quantity could provide insight into materials such as magnetic insulators and spin liquids and aid optimization of spintronic devices. ...
    • Mach-Zehnder interferometry using spin- and valley-polarized quantum Hall edge states in graphene 

      Wei, Di S.; van der Sar, Toeno; Watanabe, Kenji; Taniguchi, Takashi; Halperin, Bertrand I.; e.a. (American Association for the Advancement of Science (AAAS), 2017-08)
      Confined to a two-dimensional plane, electrons in a strong magnetic field travel along the edge in one-dimensional quantum Hall channels that are protected against backscattering. These channels can be used as solid-state ...
    • NMR technique for determining the depth of shallow nitrogen-vacancy centers in diamond 

      Pham, Linh M.; DeVience, Stephen J.; Casola, Francesco; Lovchinsky, Igor; Sushkov, Alexander O.; e.a. (American Physical Society, 2016-01)
      We demonstrate a robust experimental method for determining the depth of individual shallow nitrogen-vacancy (NV) centers in diamond with ∼1 nm uncertainty. We use a confocal microscope to observe single NV centers and ...
    • Quantum Hall Effect, Screening, and Layer-Polarized Insulating States in Twisted Bilayer Graphene 

      Sanchez-Yamagishi, Javier D.; Taychatanapat, Thiti; Watanabe, Kenji; Taniguchi, Takashi; Yacoby, Amir; e.a. (American Physical Society, 2012-02)
      We investigate electronic transport in dual-gated twisted-bilayer graphene. Despite the subnanometer proximity between the layers, we identify independent contributions to the magnetoresistance from the graphene Landau ...
    • Single-color centers implanted in diamond nanostructures 

      Hausmann, Birgit J. M.; Babinec, Thomas M.; Choy, Jennifer T.; Hodges, Jonathan S.; Hong, Sungkun; e.a. (Institute of Physics Publishing, 2011-04)
      The development of material-processing techniques that can be used to generate optical diamond nanostructures containing a single-color center is an important problem in quantum science and technology. In this work, we ...
