Busseiron is a Japanese term for a broad branch of physics focused on the study of matter.

In the mid-20th century, it expanded to include magnetism, metals and quantum theory, blurring disciplinary boundaries.

All interesting physics is decentralized and local. If there was a central algorithm deciding what physics is allowed, we wouldn't have the enormous diversity and beauty of the universe emerging out of something like two dozen fundamental physical constants.

I think this decentralized nature is also important when trying to understand physical systems. When we came up with our definition of topological order based on error correction (https://doi.org/10.1103/PhysRevB.106.085143), it was absolutely crucial to use a decentralized algorithm and not a centralized one where you feed in the positions of all errors at once. It's the fediverse approach to error correction, if you like.

Hey there, I am Prathamesh Deshmukh, a PhD scholar at UGC-DAE CSR, Mumbai, working in condensed matter physics. My research focuses on magnetoelectric coupling in multiferroic composites and their dielectric, magnetic, and neutron diffraction studies.

Beyond synthesis, I specialise in scientific instrumentation. I designed the Advanced Transport Measurement System (ATMS), a low-cost cryogenic setup for precision transport measurements, and developed PICA, an open-source Python suite for lab automation.

I will be completing my PhD this year and am seeking postdoctoral research opportunities that would leverage my expertise in experimental physics, scientific instrumentation, and software development.

Topologically ordered states of matter are characterized by fascinating non-local quantum correlations in the many-body wave function. However, deciding whether a quantum state is topologically ordered or not is extremely difficult. A large part of the problem is that so far, signatures like the topological entanglement entropy could not be efficiently computed.

We are happy to present a framework for the computation of topological order that provides an exponential speedup over existing methods: https://dx.doi.org/10.1088/1367-2630/ae3598

🧵 Post 2 / 3 — Removing Hand-Waving
🌀 Where the hand-waving usually starts
In many explanations we’re told: • “electrons form clouds”
• “bonds form by overlap”
• “Cooper pairs move without resistance”
All true — but often mechanically vague.
Using explicit phase, boundary, and flux constraints, many topics become clearer without contradicting known physics: electron orbitals, bonding (covalent/ionic/metallic), reaction selectivity, and even superconductivity (Cooper pairs, flux exclusion).
Probability remains — but it’s no longer doing all the explanatory work.

Yesterday our #cecam workshop on #uncertainty quantification (#uq)
for atomistic modelling and #machinelearning for #materials #modelling
and #chemistry started.

The opening contribution was by Niklas Schmitz from @MatMat
on #uq for #densityfuncitionaltheory:
https://github.com/niklasschmitz/tutorial-cecam-workshop-dftk-2025
building upon our recent preprint https://arxiv.org/abs/2509.07785.

New preprint https://arxiv.org/abs/2511.06957

A #perspective discussing Moreau-Yosida (MY) techniques in #densityfunctionaltheory.
MY regularisation has enabled to import tools from #convexanalysis into #dft
providing a new mathematical understanding of the most important atomistic simulation approach
and new robust algorithms for Kohn-Sham #dft.

Thanks to my co-authors from the #hylleraas centre and #oslomet for insightful discussions.

Superconductivity = zero resistance ⚡

New research digs into Cooper pair density and how it drives the superconducting state.

Big implications for quantum tech + energy.

…a family of exactly solvable #quantumspin models in one and two dimensions, in which free #paraparticles emerge as quasiparticle excitations, and their exchange statistics can be physically observed and are notably distinct from fermions and bosons…the possibility of a new type of #quasiparticle in #condensedmatter systems and—more speculatively—the potential for previously unconsidered types of #elementaryparticle.
