Quantum electrodynamics on a 1D lattice can lead to localization of charges, in contrast to the thermalizing dynamics. This study identifies the origin of such non-thermal signatures and attribute it to the fracturing of the underlying Hilbert space.

Solidarity with @uonucu.bsky.social members striking over the possible 200+ job cuts at the University of Nottingham, after 650 staff lost their jobs in the past two years.
I also share their deep concerns about new plans to suspend 48 courses, including nursing, modern languages, and music.

It's not just music and language courses- it's 48 courses across the university.
But here's the thing- our UCU colleagues at other universities (like @Cardiffucu.bsky.social) have faced the exact same threats, fought back, and won. So we can too.

I can't express how damaging this is, music and languages aren't just optional extras, they are at the core of what a university does: cultivate knowledge and culture in the next generation. And if they'll cut those, what's next? It's institutional self-destruction.

I’ve always thought the problem with quantum computers is that they don’t cost nearly enough money (ideally, at least a million dollars per kg!), and should experience heavy vibrations and crushing G-forces after being calibrated. ⚛️🧪

As a theoretical cosmologist, I'm frequently asked "what is the benefit of the work you're doing for people's lives?" Nothing I work on makes money or cures disease.
There are a few different answers one can give, at various levels of "convincing" / "actually relevant to why the work is done."

We have made it clear from the beginning: our industrial action ends as soon as the university agrees to no compulsory redundancies.
This is a demand that the university takes on the responsibility and consequences of their poor financial decisions without putting it on us.

It’s a really dire situation in UK academia.
Here at Nottingham, we’re being told to expect 20% cuts across the board. All because the university mismanaged its money: spending millions on a new campus without a plan, that now has to be sold! And now they want £50m more for a new medical building.
