We compute the sensitivies of different detectors and show that all modern detectors hare quite comparable to the dedicated high-frequency detectors. We could also build small-scale detectors which have good sensitivity in a broad band.

In fact, the sensitivity of the detectors depends on the point on the sky from where the signal is coming from. Usually, we assume the signals to come from zenith. And for such signals we're indeed not sensitive above a few kHz.
Not the case for other points on the sky (like on the image here)!

Gravitational-wave detectors currently measure signals at around 10-1000 Hz. It is not widely known, but they are also quite sensitive to GW signals at much higher frequencies — up to GHz. We don't know whether there are signals there, but wouldn't that be fun?! We wrote a paper about that!

I'm really happy to have been awarded the Rudolf Kaiser Prize in experimental physics! I got it for my experiments enhancing optical force sensors with quantum squeezed light generated inside the sensors themselves.
Feeling motivated to get back to work and do some more fun science!

A few days ago the publisher told me that my recent review was selected for the cover, and I was to provide a nice engaging picture, asap. I've never drawn nice enganing pictures, so after a night with procreate, youtube and lots (LOTS) of coffee, the best I could do was this, please be engaged :D

My old paper (title "Quantum expander for gravitational-wave observatories") made it into xkcd! :D

We recently had our new paper published with a fancy name "coherent feedback for quantum expander in gravitational-wave observatories". It's special for me, since that's the first paper where I'm the PI and had full responsibility for the project.

Love it when working on some boring simulation I get #accidental_art from the script!

Our paper on using quantum light to overcome decoherence in force sensors is finally published in PRL!
I wrote the first draft of the paper in 2017, and since then we did a lot work to improve the data quality and the understanding of physics. 5 years, crazy!
