Brendan Sheehan
Postdoctoral Associate
I am an experimental condensed matter physicist with expertise in the use of magnetic resonance techniques to manipulate spins in the solid state for quantum information. I am presently working as a postdoctoral researcher in the Quantum Spin Laboratory (group of Prof. Chandrasekhar Ramanathan) at Dartmouth, where I study many-body spin dynamics of paramagnetic centers (13C nuclei, nitrogen-vacancy (NV) centers, and substitutional nitrogen (P1) defect centers) in diamond, especially at high magnetic field.
