Gravitational waves driven by holographic dark energy
Nuclear Physics BIn this paper, we have studied the effects of holographic dark energy on the evolution of gravitational waves. The background evolution of gravitational waves in a flat FRW universe is considered and studied in the presence of various holographic dark ...

Newtonian noise and ambient ground motion for gravitational wave detectors
, 2016 Fluctuations of the local gravitational field as a result of seismic and atmospheric displacements will limit the sensitivity of ground based gravitational wave detectors at frequencies below 10 Hz.

In Situ Acoustic Monitoring of Focused Femtosecond Pulse Duration in Air
Laser &Photonics Reviews, EarlyView.Air‐breakdown acoustics at the laser focus is used to determine femtosecond pulse duration with a simple USB microphone. By chirp‐tuning and compressing 1030 nm pulses from 241 to 50 fs, the acoustic amplitude scales inversely proportional to the square root of the pulse duration, enabling in situ readout over 50 fs–5 ps—crucial for precise pulse ...

First Search for Gravitational Waves from Known Pulsars with Advanced LIGO
, 2017 We present the result of searches for gravitational waves from 200 pulsars using data from the first observing run ofthe Advanced LIGO detectors. We find no significant evidence for a gravitational-wave signal from any of thesepulsars, but we are able to

Traces of Extra Dimensions in Cosmology [PDF]
, 2010 In this thesis, we discuss the observational consequences of extra dimensions on cosmological phenomena. We begin with an overview of extra dimensions, from the initial ideas of Kaluza and Klein to the more recent concept of braneworld models and in ...

Experimental Study on Polymer–Polymer Interfacial Thermal Resistance
Macromolecular Theory and Simulations, Volume 34, Issue 2, March 2025.Interfacial thermal resistance (ITR) in polymer–polymer interfaces is experimentally measured in this paper by the multi‐layered bulk sample approach. Based on numerical simulation and experimental verification, new techniques of layer‐overlapping samples are developed.
