RE: https://mastodon.social/@europeanphysicalsociety/115966229883497497 The European Physical Society is now posting their materials also on here. Let’s give them a warm welcome and a reason to be even more active. ❤️ #physics

I am still alive, and there are big news for the project – news that are over one month overdue, but I was so focused on writing grant proposals that I couldn’t find time to write about it. Long story short: we finished the preprint of our spin liquid paper ( […] [Original post on fediscience.org]

⚛️ News from quantum physics: So-called Anyons are exotic particles that are neither bosons nor fermions. A team from Innsbruck, Brussels, and Paris has found a simple yet powerful way to detect anyons—by swapping two spins. 🆕 […]

On Friday 4th of July I will give a talk on Bazyliszek sci-fi/fantasy convention in Warsaw, Poland. I will talk about 2D physics (mostly anyons), starting from literary visions of 2D worlds like Flatland or Planiverse. The admission to the whole convention […] [Original post on fediscience.org]

Anyons are quasiparticles that differ from the familiar fermions and boson. Scientists led by Hanns-Christoph Nägerl have observed anyons in a one-dimensional quantum system for the first time. The results, published in Nature, may contribute to a better […] [Original post on social.uibk.ac.at]

We just submitted the first QUINTO draft of paper to a journal. Let's see what the editors and reviewers think. The paper is about fractional quantum Hall states in atomic arrays. Here is the popular summary we submitted alongside: "When atoms are arranged […] [Original post on fediscience.org]

We just came back from the "Light-Matter Interactions and Collective Effects" workshop in Paris. We heard some interesting talks on how quantum emitters (not only atoms, but also e.g. molecules and quantum dots) interact with each other and how people try to […] [Original post on fediscience.org]

This picture demonstrating the utility of ladder operators for the quantum harmonic oscillator in Griffith's book is just absolutely charming. ⚛️🧪 #Science #Physics #EduSky #QuantumMechanics

I was very happy to see that several of my friends, mentors, and colleagues, including Ali Yazdani and Joe Orenstein, signed this “Open Letter to the American People” in support of science from current elected members of the National Academies of Sciences, Engineering, and Medicine. Please share […]

Fractional quantum Hall states in atom arrays Our second approach to create a topological order in atom arrays is to focus on a different kind of topological order: fractional quantum Hall (FQH) states. These were first discovered in condensed matter. It is […] [Original post on fediscience.org]

So today is the birthday of Amalie Emmy Noether. I cannot speak competently about her work in pure mathematics - in other words, the majority of her ground-breaking accomplishments elude me somewhat. But as a theoretical physicist, I can speak about her […] [Original post on astrodon.social]

Spin liquids in Rydberg atom arrays in cavities What is our proposal for the realization of spin liquid? We consider an atom array held by optical tweezers and placed in an optical cavity. The cavity consists of two mirrors placed on the opposite sides of […] [Original post on fediscience.org]

I'm finally unveiling the #activitypub project that has been consuming my weekends: Encyclia, an #orcid bridge that will make ORCID records followable and interactable on the fediverse. 🙂 It's early-stage and the ORCID following function is not publicly available yet. We're seeking community […]

#Microsoft has announced that they created topological qubits. The perspective of creating such qubits is one of the main reasons why scientists are interested in topological orders. A topological qubit will be based on the operations of braiding anyons (see my post about anyons here […]

Atom arrays Scientists have developed ways of trapping atoms and arranging them in space using laser beams (such as “optical tweezers” and “optical lattices”). What can one do using these tools? One possibility is arranging the atoms in a regular array […] [Original post on fediscience.org]

Quantum simulation of topological orders In the previous posts, I was talking a lot about complex quantum states that we aim to study in the QUINTO project: topological orders, in particular spin liquids. Now, let us see how quantum optics can help us in […] [Original post on fediscience.org]

Anyons in spin liquids To see how anyons can arise in topological orders, one can look again on the simplified picture of the Z2 spin liquid (see the previous post:). Anyons can be created on the top of the spin liquid by altering the singlet pattern […] [Original post on fediscience.org]
