Quantum Phase Extraction in Isospectral Electronic Nanostructures
Christopher R. Moon, Laila S. Mattos, Brian K. Foster +3
Quantum phase is not a direct observable and is usually determined by interferometric methods. We present a method to map complete electron wave functions, including internal quant…
An off-board quantum point contact as a sensitive detector of cantilever motion
M. Poggio, M. P. Jura, C. L. Degen +4
Recent advances in the fabrication of microelectromechanical systems (MEMS) and their evolution into nanoelectromechanical systems (NEMS) have allowed researchers to measure extrem…
Nuclear spin relaxation induced by a mechanical resonator
C. L. Degen, M. Poggio, H. J. Mamin +1
We report on measurements of the spin lifetime of nuclear spins strongly coupled to a micromechanical cantilever as used in magnetic resonance force microscopy. We find that the ro…
The role of spin noise in the detection of nanoscale ensembles of nuclear spins
C. L. Degen, M. Poggio, H. J. Mamin +1
When probing nuclear spins in materials on the nanometer scale, random fluctuations of the spin polarization will exceed the mean Boltzmann polarization for sample volumes below ab…
Fractional Charge and Quantized Current in the Quantum Spin Hall State
Xiao-Liang Qi, Taylor L. Hughes, Shou-Cheng Zhang
A profound manifestation of topologically non-trivial states of matter is the occurrence of fractionally charged elementary excitations. The quantum spin Hall insulator state is a…
Quantum Spin Hall Insulator State in HgTe Quantum Wells
Markus Koenig, Steffen Wiedmann, Christoph Bruene +5
Recent theory predicted that the Quantum Spin Hall Effect, a fundamentally novel quantum state of matter that exists at zero external magnetic field, may be realized in HgTe/(Hg,Cd…
