Circular polarization of gravitational waves from early-Universe helical turbulence

Physical Review Research, 2021
We perform direct numerical simulations to compute the net circular polarization of gravitational waves from helical (chiral) turbulent sources in the early Universe for a variety of initial conditions, including driven (stationary) and decaying ...

Backpropagation Through Soft Body: Investigating Information Processing in Brain–Body Coupling Systems

Advanced Robotics Research, EarlyView.
This study explores how information processing is distributed between brains and bodies through a codesign approach. Using the “backpropagation through soft body” framework, brain–body coupling agents are developed and analyzed across several tasks in which output is generated through the agents’ physical dynamics.

Detection Rate of Galaxy Cluster-lensed Stellar Binary Black Hole Mergers by the Third-generation Gravitational-wave Detectors

The Astrophysical Journal
Gravitational waves (GWs) from stellar binary black hole (sBBH) mergers can be strongly gravitational lensed by intervening galaxies/galaxy clusters. Only a few works have investigated cluster-lensed sBBH mergers by adopting oversimplified models, while ...

Short-period AM CVn systems as optical, X-ray and gravitational-wave sources [PDF]

, 2003
We model the population of AM CVn systems in the Galaxy and discuss the detectability of these systems with optical, X-ray and gravitational-wave detectors.

Study of Free‐Space Optical Quantum Network: Review and Prospectives

Advanced Science, EarlyView.
Free from the constraints of fiber connections, free‐space quantum network enables longer and more flexible quantum network connections. This review summarizes and comparatively analyzes free‐space quantum network experiments based on ground stations, satellites, and mobile platforms.

Lunar‐Based Photothermal CO2 Reduction Strategy: Self‐Evolving Transient Active Interface and Band Engineering

Advanced Science, EarlyView.
A self‐evolving Pd/Ov‐FeTiO3 photothermal catalyst, inspired by lunar soil, enables efficient extraterrestrial CO2 conversion. The formation of transient active interfaces and oxygen vacancies extends light absorption to the infrared range and optimizes electron transfer.

Characterizing Light Scattering Sources in Gravitational-Wave Interferometers [PDF]

, 2023
openStray light in gravitational wave interferometers causes unwanted noise in the detections and can be generated due to the scattering of light on the optics and mechanical components of the instrument.

Laboratory sources of gravitational waves

Journal of Physics: Conference Series, 2020
Abstract We consider the possibility of generating and subsequently detecting artificial gravitational waves in a laboratory based on different approaches. As one of the methods for creating gravitational waves, we investigate oscillations of the ions of the crystal lattice of a dielectric under the influence of high-power laser ...

The Effect of Mass Segregation on Gravitational Wave Sources near Massive Black Holes [PDF]

, 2006
Gravitational waves (GWs) from the inspiral of compact remnants (CRs) into massive black holes (MBHs) will be observable to cosmological distances. While a CR spirals in, two-body scattering by field stars may cause it to fall into the central MBH before
