Grey‐Body Factors and Absorption Cross‐Sections of Scalar and Dirac Fields in the Vicinity of Dilaton‐De Sitter Black Hole

open access: yesFortschritte der Physik, Volume 74, Issue 1, January 2026.
Abstract The propagation of a massive scalar field and a massless Dirac field in the geometry of a dilaton–de Sitter black hole is investigated. Starting from the covariant perturbation equations, the corresponding effective potentials are presented and their dependence on the dilaton charge, field mass, and cosmological constant is analyzed. Using the

Displacement and Vibration Measurements with Interferometers: Benchmark Configurations, Performance, and R&D Opportunities

open access: yesAdvanced Photonics Research, Volume 6, Issue 12, December 2025.
Self‐mixing interferometry is a powerful technique that brings together the exceptional sensitivity of phase measurements with the unequalled simplicity of the self‐mix configuration based on modulation of the cavity field induced by the return from the target. According to the selected measurand, displacement or vibration, and to the analog of digital

Gravitational waves in Newton’s gravitation and criticism of gravitational waves resulting from the General Theory of Relativity (LIGO)

open access: yesҚарағанды университетінің хабаршысы. Физика сериясы, 2019
The most important conclusion from this article is that from the General Theory of Relativity do not result any gravitational waves, but just ordinary modulation of the gravitational field intensities caused by rotating of bodies.

Photonic Metrology with Hierarchic Quantum Frequentist Bounds

open access: yesAdvanced Photonics Research, Volume 6, Issue 12, December 2025.
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.

Search for compact dark matter objects in the solar system with LIGO data

open access: yesPhysics Letters B, 2020
Dark matter could be composed of compact dark objects (CDOs). A close binary of CDOs orbiting in the interior of solar system bodies can be a loud source of gravitational waves (GWs) for the LIGO and VIRGO detectors.

Status of LIGO [PDF]

open access: yesSPIE Proceedings, 2003
LIGO construction has been completed. The three interferometers at the two LIGO observatory sites (Livingston, Louisiana and Hanford, Washington) have been operated successfully as power-recycled Michelson interferometers with Fabry-Perot arm cavities.
