XRISM High-resolution Spectroscopy of SS 433: Evidence of Decreasing Line-of-Sight Velocity Dispersion along the Jet

Megumi Shidatsu, Shogo Kobayashi, Yusuke Sakai, Toshihiro Takagi, Yuta Okada, Shinya Yamada, Yoshihiro Ueda, Hideki Uchiyama, Robert Petre · 2025

We report on the jet structure in SS 433 based on X-ray high resolution spectroscopy with the XRISM/Resolve. The source was observed over 5 days covering both inside and outside an eclipse of the comp…

Effective Infection Opportunity Population (EIOP) Hypothesis in Applying SIR Infection Theory

Hiroshi Isshiki, Masao Namiki, Takeshi Kinoshita, Ryosuke Yano · 2020

The SIR infection theory initiated by Kermack-Mckendrick in 1927 discusses the infection in an isolated population with uniform properties such as the uniform population distribution. In the infection…

Sub-100-as timing jitter optical pulse trains from mode-locked Er-fiber lasers

Tae Keun Kim, Youjian Song, Kwangyun Jung, Chur Kim, Hyoji Kim, Chang Hee Nam, Jungwon Kim · 2011

We demonstrate sub-100-attosecond timing jitter optical pulse trains generated from free-running, 77.6-MHz repetition-rate, mode-locked Er-fiber lasers. At -0.002(\pm0.001) ps2 net cavity dispersion, …

Limit Theorems For Quantum Walks Associated with Hadamard Matrices

Clement Ampadu · 2011

We study a one-parameter family of discrete-time quantum walk models on the line and in the xy-plane associated with the Hadamard walk. Weak convergence in the long-time limit of all moments of the wa…

On the Ambainis-Bach-Nayak-Vishwanath-Watrous Conjecture

Clement Ampadu · 2010

We show the flaw in a theorem of Konno, Namiki, Soshi, and Sudbury in [3] and provide the necessary correction in the case of the Finite Hadamard walk and use it to show that a conjecture of Ambainis,…

Measurement Theory in Lax-Phillips Formalism

S. Tasaki, E. Eisenberg, L. P. Horwitz · 1993

It is shown that the application of Lax-Phillips scattering theory to quantum mechanics provides a natural framework for the realization of the ideas of the Many-Hilbert-Space theory of Machida and Na…

Treatment of Constraints in Stochastic Quantization Method and Covariantized Langevin Equation

K. Ikegami, T. Kimura, R. Mochizuki · 1992

We study the treatment of the constraints in stochastic quantization method. We improve the treatment of the stochastic consistency condition proposed by Namiki et al. by suitably taking account of th…
