Exploration of optimal hyperfine transitions for spin-wave storage in Er:YSiO
K. Matsuura, S. Yasui, R. Kaji +3
The dependence of the magnetic fluctuations and the spin coherence time of the lowest Stark states in Er:YSiO under zero…
Semiconductor Nanopillar as a Single-Photon Emitter and its Optimal Design
S. Odashima, H. Sasakura
The semiconductor quantum dot nanopillar array in InAs/GaAs was fabricated. In consideration of the quantum dot density, the pillar diameter was determined as only a few quantum do…
Third Stable Branch and Tristability of Nuclear Spin Polarization in Single Quantum Dot System
Sota Yamamoto, Reina Kaji, Hirotaka Sasakura +1
Semiconductor quantum dots provide a spin-coupled system of an electron and nuclei via enhanced hyperfine interaction. We showed that the nuclear spin polarization in single quantu…
Fiber-coupled pillar array as a highly pure and stable single-photon source
Satoru Odashima, Hirotaka Sasakura, Hideaki Nakajima +1
A highly pure and stable single-photon source is prepared that comprises a well-designed pillar array in which each pillar contains only a few InAs quantum dots. A nano-pillar in t…
Dynamic nuclear spin polarization in self-assembled quantum dots under zero magnetic field
Ryosuke Matsusaki, Reina Kaji, Sohta Yamamoto +2
We studied the zero-field dynamic nuclear spin polarization in a single InAlAs/AlGaAs quantum dot. Even without any external magnetic field, the p…
Size distribution of islands according to 2D growth model with 2 kinds of diffusion atoms
R. Yamauchi, X. M. Lu, M. Koyama +3
We simulated the growth of 2D islands with 2 kinds of diffusion atoms using the kinetic Monte- Carlo (kMC) method. As a result, we found that the slow atoms tend to create nuclei a…
