Oxygen isotope fractionation in the Martian atmosphere induced by CO photolysis and O formation
Tatsuya Yoshida, Shohei Aoki, Hiromu Nakagawa +8
The enrichment of heavy isotopes of volatile elements in the Martian atmosphere indicates that Mars lost a large portion of its atmosphere through escape to space. Recent atmospher…
Photon-Assisted Tunneling in Double Quantum Dot: Application of Scattering Theory
Miyu Umebayashi, Mikio Eto
We theoretically examine the photon-assisted tunneling (PAT) in a double quantum dot (DQD) in parallel when one of the quantum dots (QDs) is irradiated by an AC field. First, we fo…
Evaluating the solution performance of the augmented Lagrangian function on Ising machines
Shunsuke Awai, Takuro Itoh, Keita Takahashi +2
We apply the augmented Lagrangian function (ALF) as a formulation for Ising machines and evaluate its performance by time-to-epsilon (\mathrm{TT\varepsilon}). The ALF has been well…
