Nanometre-scale probing of spin waves using single electron spins
Toeno van der Sar, Francesco Casola, Ronald Walsworth +1
Correlated-electron systems support a wealth of magnetic excitations, ranging from conventional spin waves to exotic fractional excitations in low-dimensional or geometrically-frus…
Decoherence imaging of spin ensembles using a scanning single-electron spin in diamond
Lan Luan, Michael S. Grinolds, Sungkun Hong +3
The nitrogen-vacancy (NV) defect center in diamond has demonstrated great capability for nanoscale magnetic sensing and imaging for both static and periodically modulated target fi…
High-efficiency resonant amplification of weak magnetic fields for single spin magnetometry
Luka Trifunovic, Fabio L. Pedrocchi, Silas Hoffman +3
We demonstrate theoretically that by placing a ferromagnetic particle between a nitrogen-vacancy (NV) magnetometer and a target spin, the magnetometer sensitivity is increased dram…
Detecting Majoranas in 1D wires by charge sensing
Gilad Ben-Shach, Arbel Haim, Ian Appelbaum +3
The electron number-parity of the ground state of a semiconductor narowire proximity-coupled to a bulk superconductor can alternate between the quantised values if paramete…
Nanoscale NMR Spectroscopy and Imaging of Multiple Nuclear Species
Stephen J. DeVience, Linh M. Pham, Igor Lovchinsky +10
Nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI) are well-established techniques that provide valuable information in a diverse set of disciplines but are curr…
Field-effect-induced two-dimensional electron gas utilizing modulation doping for improved ohmic contacts
Sumit Mondal, Geoffrey C. Gardner, John D. Watson +3
Modulation-doped AlGaAs/GaAs heterostructures are utilized extensively in the study of quantum transport in nanostructures, but charge fluctuations associated with remote ionized d…
