    • Anion Stabilization in Electrostatic Environments 

      Olivares-Amaya, Roberto; Stopa, Michael P; Andrade, Xavier; Watson, Mark A.; Aspuru-Guzik, Alan (American Chemical Society, 2011)
      Excess charge stabilization of molecules in metallic environments is of particular importance for fields such as molecular electronics and surface chemistry. We study the energetics of benzene and its anion between two ...
    • Dynamic Nuclear Polarization in Double Quantum Dots 

      Gullans, Michael John; Krich, Jacob Jonathan; Taylor, Jacob Mason; Bluhm, Hendrik; Halperin, Bertrand I.; Marcus, Charles Masamed; Stopa, Michael P; Yacoby, Amir; Lukin, Mikhail D. (American Physical Society, 2010)
      We theoretically investigate the controlled dynamic polarization of lattice nuclear spins in GaAs double quantum dots containing two electrons. Three regimes of long-term dynamics are identified, including the buildup of ...
    • Fast Sensing of Double-Dot Charge Arrangement and Spin State with a Radio-Frequency Sensor Quantum Dot 

      Barthel, Christian; Kjærgaard, M.; Medford, James Redding; Stopa, Michael P; Marcus, Charles Masamed; Hanson, M. P.; Gossard, Arthur C. (American Physical Society, 2010)
      Single-shot measurement of the charge arrangement and spin state of a double quantum dot are reported with measurement times down to 100 ns. Sensing uses radio-frequency reflectometry of a proximal quantum dot in the Coulomb ...
    • Measurement of the Absolute Raman Cross Section of the Optical Phonon in Silicon 

      Aggarwal, R. L.; Farrar, L. W.; Saikin, S. K.; Aspuru-Guzik, Alan; Stopa, M; Polla, D. L. (Elsevier BV, 2011)
      The absolute Raman cross section \(\sigma_{RS}\) of the first-order \(519 cm^{−1}\) optical phonon in silicon was measured using a small temperature-controlled blackbody for the signal calibration of the Raman system. ...
