Standard quantum limit of finite-size optical lattice clock in estimating gravitational potential
Fumiya Nishimura, Yui Kuramochi, Kazuhiro Yamamoto
We evaluated the accuracy limit for estimating gravitational potential using optical lattice clocks by utilizing the quantum Cramér--Rao bound. We then compared the results for sin…

Meeting time distributions in Bernoulli systems
A. Akaishi, M. Hirata, K. Yamamoto +1
Meeting time is defined as the time for which two orbits approach each other within distance in phase space. We show that the distribution of the meeting time is exponential in…
