Computational study of alpha-ray induced electron excitation in diamonds for radiation detection
Atsuhiro Umemoto, Yoshiyuki Miyamoto
To investigate the mechanism of radiation detection in diamonds, we developed a real time time dependent density functional theory based calculation scheme to evaluate changes in t…
Identical Photons from Multiple Tin-Vacancy Centers in Diamond
Yasuyuki Narita, Peng Wang, Kazuki Oba +5
We report the narrow inhomogeneous distribution of the zero-phonon line from tin-vacancy (SnV) centers in diamond and the overlap of spectra from multiple separated SnV centers. Ph…
Low-Temperature Spectroscopic Investigation of Lead-Vacancy Centers in Diamond Fabricated by High-Pressure and High-Temperature Treatment
Peng Wang, Takashi Taniguchi, Yoshiyuki Miyamoto +2
We report the optical observation of lead-vacancy (PbV) centers in diamond fabricated by Pb ion implantation and subsequent high-temperature annealing (2100 °C) under high pressure…
First Principles Study of the Optical Dipole Trap for Two-Dimensional Excitons in Graphane
Hiroki Katow, Ryosuke Akashi, Yoshiyuki Miyamoto +1
Recent studies on excitons in two-dimensional materials have been widely conducted for their potential usages for novel electronic and optical devices. Especially, sophisticated ma…
{\it Ab initio} approach to the lattice softening of an Al slab driven by collective electronic excitations after ultrashort laser pulse irradiation
Hiroki Katow, Yoshiyuki Miyamoto
Recent advances in ultrashort laser pulse techniques have opened up a wide variety of applications in both fundamental physics and industrial fields. In this work, mo…
Tin-Vacancy Quantum Emitters in Diamond
Takayuki Iwasaki, Yoshiyuki Miyamoto, Takashi Taniguchi +4
Tin-vacancy (SnV) color centers were created in diamond by ion implantation and subsequent high temperature annealing up to 2100 °C at 7.7 GPa. The first-principles calculation sug…
