Imaging of high-frequency electromagnetic field by multipulse sensing using nitrogen vacancy centers in diamond
Shintaro Nomura, Hideyuki Watanabe, Satoshi Kashiwaya
Near-field enhancement of the microwave field is applied for imaging high frequency radio field using a diamond chip with an -doped isotopically purified diamond layer grown by…
Angle dependence of N nuclear spin dynamics in diamond NV centers
Yusuke Azuma, Shintaro Nomura, Hideyuki Watanabe +1
We report on the dynamics of the Rabi oscillation and the Larmor precession of N nuclear spin using nonselective short microwave pulses for initialization of N nuclea…
Imaging of microwave field distribution over a non-fed gold pattern by using NV centers in diamond
Giacomo Mariani, Shuhei Nomoto, Satoshi Kashiwaya +1
Nitrogen-vacancy (NV) centers in diamond have been widely used as platforms for quantum information, magnetometry and imaging of microwave (MW) fields. High-precision spatial contr…
Importance of Initial Electronic State in Two-Dimensional Electron System for Electron Transport from Two-Dimensional Electron Gas to Quantum Dot
Masakazu Muraguchi, Yukihiro Takada, Shintaro Nomura +2
We have theoretically investigated the time-evolution of electron transport from a two-dimensional electron system (2DES) to a quantum dot (QD). We clearly showed that the coherent…
Aharonov-Bohm Oscillations in Photoluminescence from Charged Exciton in Quantum Tubes
Kohei Tsumura, Shintaro Nomura, Pamela Mohan +2
The oscillation of photoluminescence peak energies is observed in InAs quantum tubes depending on the magnetic flux through the tube. The oscillation is shown to be due to the Ahar…
Linear scaling calculation of a n-type GaAs quantum dot
Shintaro Nomura, Toshiaki Iitaka
A linear scale method for calculating electronic properties of large and complex systems is introduced within a local density approximation. The method is based on the Chebyshev po…
