Decoherence Imaging of Spin Ensembles Using a Scanning Single-Electron Spin in Diamond

January 29, 2015
Fig. 1

Figure 1: Detecting surface electron spin ensembles using a scanning magnetometer composed of a single nitrogen-vacancy (NV) spin. (a): Schematic of the experiment. The NV spin resides in a nanopillar fabricated on a diamond scanning platform, with distance d from the sample surface. The angle between the normal direction of the surface and the quantization axis of the NV spin θ is imposed by crystallographic directions. The NV spin is optically initialized and read out from above. A nearby antenna is used to apply microwave pulses to manipulate the NV spin state coherently.

Harvard Physics Research Poster Session

January 28, 2015

The physics Graduate Student Council (GSC) organized the Harvard Physics Research Poster Session with the intent of increasing intra-departmental communication between graduate students. Senior grad students working in physics labs presented their research to a fellow grad student audience who are either looking for a lab to join or who are simply curious about physics research. The GSC plans to organize this event annually.

See the slideshow of the event.

The Everest Simulation: Harvard Business School Comes to the Physics Department

January 23, 2015
Mount Everest

On January 21, 2015,  Willy Shih, Robert and Jane Cizik Professor of Management and Practice at the Harvard Business School, gave a leadership workshop to 30 of our Research Scholars. In teams of five, with each person assigned a specific role, scholars used a computer simulation to climb Mt. Everest.  You’ll have to talk with the participants to find out how their teams fared!

Figure 2: Inner structure of the skyrmion in the (x, z) plane. (a) In-trap SF densities of the |+1〉 (|−1〉) bosons form a vortex (antivortex) around the equator, whereas that of the |0〉 condensate in (b) creates a dark soliton at the poles. [from M.
