Broadband resonant amplifier?

Beats me. It sounds like an English language science reporter who has got a firm grasp on the wring end of the stick.

We will probably have to wait until it gets written up in New Scientist or Physics Today before we can get a sensible idea of what might be going on.

NS will scramble it just as comprehensively.

However, their paper is now published in Nature and seems to be genuine in the sense that their parametric resonance phonon amplification trick may extend sensitivity of the LIGO interferometer to lower frequencies as well as boosting the available gain.

Fig 1 if you want to see what the claim it can do.

If they are right it gets at least one order of magnitude improvement in sensitivity and nearly two orders of magnitude more at some frequencies.

It is a very difficult read even for physicists. I can't claim to understand it after reading through the first time but equally it does look at least plausible. Needs more time than I can give it right now. Phil Hobbs is your best bet on the practicalities of this one.

Thanks. It's late here, and I won't look at properly it until tomorrow morning, but it doesn't look like something that going to be useful all that often ..

Institutes and universities now have PR departments, and I suppose they have quotas for press releases.

Be fair! Their paper was published in Nature which is a highly reputable scientific journal - it isn't their fault that journalists have scrambled it for popular consumption. It isn't an easy read either...

Phil H is my best guess at someone who can make sense of it or might even possibly know someone who is working on its implementation.

I just looked at that headline and thought "Broadband resonant" sounds like an oxymoron! I'll wait for something to appear in NS. But it is true that their articles are mostly written by journalists rather than researchers these days...
