Comparison of simulation tools for LCGT
I am comparing several simulation tools with theoretical line using LCGT 2007 parameters. I used here FINESSE, Thomas, Oprickle. Except for FINESSE, all results matched pretty well within 0.1%-1% accuracy. FINESSE seems to have a bug of a factor by sqrt(2), but it can be compensated later if you know this information.
- Theoretical: just analytical way shown in LCGT document on page xx.
- FINESSE: Developped by Andreas Freise. C based. 'ps2S' and 'scale meter' commands are used for the unit in m/rHz and 'fig' command are used to produce excitations in frequency domain. Compensation factor *sqrt(2) was needed to match other results. This could be a bug.
- Thomas: Developped by Thomas Cobit. Visual C++ besed, running only Windows machine. This is the first simulation tool which can calculate quantum effect including raddiation pressure effect. For shotnoise calculation, just very hevy masses are used to compare shotnoise above.
- Optickle: Developped by Matt Evans. Matlab based, very flexible simulation tool. You can use a full set of Matlab functions. This tool also can calculate full quantum effect.
