Photonic Metrology with Hierarchic Quantum Frequentist Bounds

open access: yesAdvanced Photonics Research, EarlyView.
This paper proposes photonic metrology with hierarchical quantum frequentist bounds. The present model tightens the Quantum Cramér‐Rao Bound using a hybrid classical‐quantum framework. The experiment validates the hierarchical frequentist bounds for single‐qubit phase estimation.

Parametric instabilities in the LCGT arm cavity

open access: yes, 2008
We evaluated the parametric instabilities of LCGT (Japanese interferometric gravitational wave detector project) arm cavity. The number of unstable modes of LCGT is 10-times smaller than that of Advanced LIGO (U.S.A.).

Disentangling the potential dark matter origin of LIGO's black holes

open access: yes, 2017
The nature of dark matter remains one of the biggest open questions in physics. Intriguingly, it has been suggested that dark matter may be explained by another recently observed phenomenon: the detection of gravitational waves by LIGO.

Search for Eccentric Binary Neutron Star Mergers in the first and second observing runs of Advanced LIGO

open access: yes, 2020
We present a search for gravitational waves from merging binary neutron stars which have non-negligible eccentricity as they enter the LIGO observing band. We use the public Advanced LIGO data which covers the period from 2015 through 2017 and contains $\
