Fabry-Perot Cavity

A detailed analysis of optics related to Fabry-Perot cavity. We derive the reflections/transmission coefficients and finesse. We also show how the bullseye pattern emerge. Find the web-page …

Gravitational-Wave Stochastic Background from Kinks and Cusps on Cosmic Strings

We compute the contribution of kinks on cosmic string loops to stochastic background of gravitational waves (SBGW). We find that kinks contribute at the same order as cusps to the SBGW. We discussthe accessibility of the total background due to kinks …
