Hannover, 16 – 20 June 2013, “Fundamental noise sources” by Prof. Roman Schnabel

The “Fundamental Noise Sources” workshop took place in Mardorf (Germany) on 16 – 20 June 2013.

The workshop of the Hannover Institute is a lecture and project planning week of first and second year PhD students. A significant part of the lectures targets experimental issues. There are lectures on thermal noise spectral densities in laser interferometers coming from mirror substrates and pendulum suspensions. Lectures also cover the generation and detection of squeezed light and review opto-mechanical experiments. Other lectures focus on purely theoretical aspects such as “sources of gravitational waves”. Another significant part of the week is dedicated to “project planning”: Groups of e.g. 6 PhD students design ‘their optimum gravitational wave detector’. The goal is to achieve a high sensitivity to some particular astro-physical source, taking into account noise sources such as thermal noise, quantum noise and coupling to seismic motion.  


The week comprises 15 lectures of three different topics on Gravitational Wave Astronomy:

  • Experimental GW Physics (6 lectures )
  • General Relativity (5 lectures)
  • Data Analysis (5 lectures)
