I just came here to tell you that you should try @bluesky if you still haven't. After a few days using it, it really feels like recovering a space they took from us. You can find me there as https://t.co/cAQHARR1w9 Seriously, leave X and don't look back.

I want to finish by thanking my amazing collaborators, specially @TVZache. This was a long and challenging project, and it could not have succeed without their help and support.

Personally, this was a very special project, since I started thinking how to simulate similar gauge theories during my master thesis. During the last decade, Rydberg simulators have developed tremendously, allowing us to bring these theoretical ideas to an experimental reality.

In summary, our experiments confirm string breaking in (2+1)D both in equilibrium and non-equilibrium. These results nicely complement the very recent observations of similar phenomena with superconducting qubits and trapped ions: https://t.co/VCpklWJsyM https://t.co/zY7o56Ercw

Finally, we quench these string states and investigate the dynamics of string breaking. We observe a high-order process where the initial string maximally breaks when it has the same energy as the broken string. We characterize this resonance through many-body spectroscopy.

Moreover, strings in (2+1)D can fluctuate between different shapes, and we indeed observe all of them in the states we prepare.

We map out the phase diagram of the gauge theory by preparing the ground state adiabatically. We observe how, as we increase the Rydberg interactions (and thus the confining potential), the probability of the broken string dominates, signalling string breaking in equilibrium.

In the experiment, we can prepare and measure states corresponding to both unbroken and broken string configurations 👇🏽

Here we encode a U(1) gauge theory in a Rydberg atom array, where atom configurations naturally map to particles and strings since: 1) The local (gauge) symmetry emerges from the Rydberg blockade. 2) Long-range Rydberg interactions give rise to a confining potential.

These new particles can be detected in particle accelerators, but string breaking was never observed directly. Moreover, simulating the dynamics of this process is very challenging. Both problems can be overcome using quantum simulators with spatio-temporal resolution.

String breaking occurs in gauge theories such as quantum chromodynamics, where quarks are confined into composite objects (e.g. protons), connected by strings of gauge field. When quarks are separated, the energy increases until new particles are created, breaking the string.

I am offering a 4 year PhD position to work on quantum algorithms for many-body problems, to stat in Winter of 2025. Please do forward the announcement to potentially interested candidates!

There's a popular narrative here that says immigrants are destroying Western culture. I'd like to assert the opposite: immigrants are not only contributing to Western culture, they are often saving parts of it. Let's explore. 🧵
