I note that this work spans much beyond the QUINTO project (see the long acknowledgements list) and was started four years ago. I joined the group in @icfo.eu two years ago and contributed mostly numerical calculations;.

Also, this work naturally fits with real experimental attempts to couple Rydberg arrays with optical cavities.
[8/9]

Can we use the cavity to measure the anyonic excitations? Can the fact that the S=0 manifold is dark to the cavity (emits no photons into the cavity) be used to prepare the states?
[7/9]

Our work opens up a number of questions: what happens with anyonic excitations with S=1? How can we understand the spin liquid if the whole theory of such systems (topological order) is based on assumption of locality, while our system is clearly nonlocal?
[6/9]

This works only in S=0 sector, but it is enough, as the S=0 sector of the corresponding Heisenberg models often can host spin liquids - paradigmatic strongly-correlated phase characherized by emergent gauge fields and anyonic excitations
[5/9]

Without the cavity, the Rydberg system is a classical Ising antiferromagnet. However, addition of the cavity turns the Ising model into a Heisenberg model via a counterintuitive but simple projection mechanism.
[4/9]

Here, we turn the conventional wisdom on its head, showing that the cavity can actually be a *resource* pushing systems into strong correlation. What we need is to look at the S=0 manifold of the total spin and enrich it with local structure by adding a Rydberg interaction between atoms
[3/9]

Why is it unexpected? An optical cavity generates equal-strength all-to-all interaction between atoms. This is usually associated with a large collective spin that can be described within the mean-field framework, incompatible with the strongly-correlated physics like spin liquids.

It seems that the quantum info community is well represented on bsky, there is some quantum optics and cold atoms, but I didn't find many representatives of theoretical condensed matter or solid state physicists. Maybe that's because I started my search with quantum opticians.

While the presence on Mastodon is important (open source FTW!), I decided to open an account here, especially to advertise a major preprint (partly coming from our project, but bigger than that) that will appear on Arxiv soon.
[3/3]

We started in 2024 and were previously on Mastodon and Facebook (the latter rather for the outreach for Polish audiences as I'm originally from Poland), but the number of quantum physicists on Mastodon is quite limited especially since qubit-social.xyz no longer exists.
