Working notes

Magnetic state evolution.

The magnet track at IQ Intel, working with Subatomic Computing on magnetic-lattice systems. Findings land here as they are cleared for release.

On being late to publish

Anyone watching IQ Intel's output cadence will notice the magnet track has been quieter than the cathode side. That is accurate. It is not because we have not been working hard. It is because the engine we have been working with is unusual enough that our prior toolchain did not survive contact with it intact.

Subatomic Computing emerges microstates from the Hamiltonian rather than computing properties for configurations we specify. The shape of the output, the structure of the data, the way state evolution gets represented — none of it lines up with what magnet researchers are used to handling. We have spent significant effort porting the post-processing tooling our division depends on into a form that talks to the engine's native output, and significant additional effort on the interpretive framework that surrounds it. That work was not optional. It also was not the kind of work that produces blog-ready findings.

The tooling is now in place. The results have been flowing for some time. The first finding I am cleared to write up is on its way, and there is more behind it than I expect to publish soon. We are catching up.

What Subatomic Computing does, from where I sit

The shortest framing I can offer: the engine emerges the relevant physics organically, and that changes what is available to study. Magnetic state evolution under driven and post-pulse dynamics has been a hard problem in this field for as long as it has been a field. The configurations that determine real magnetic behavior are not always the configurations a researcher would enumerate in advance. The dynamical pathways between those configurations are even harder to enumerate, and they are usually where the interesting physics lives.

Subatomic Computing does not require the enumeration. It evolves the encoded system under Hamiltonian structure and parameterized settings, and the microstates that matter surface from the run. What I am seeing across the work that has been running on our division's lattices: the engine consistently produces microstate evolution that is structured, reproducible across independent runs, and shows behavior that is hard to assemble from anything else our group has access to.

That is not a marketing statement. It is what the data has been doing.

What is coming through this repository

Each post here is a working note rather than a polished paper. The format is a deliberate choice: I write things up when the finding is solid enough to share but before it has been laundered through the usual review cycles. That preserves something useful for the audience I expect to be reading — magnet researchers, quantum many-body theorists, people working on driven and dissipative systems — who can read a working note critically and form their own assessment without needing the conclusion handed to them in finished form.

Findings will be presented with their supporting evidence explicit. Where claims are quantitatively calibrated, that will be stated. Where claims are directionally supported but not yet quantitatively pinned down, that will be stated too. Where the engine returns warnings about a particular regime, those warnings will appear in the post rather than being suppressed. The audience can read past those caveats or take them seriously on their own judgment.

The first finding cleared for publication concerns interesting corner physics in the parameter space we have been sweeping. The methodology is direct enough to describe; some of the values are not yet ready for public release. There is a queue of additional findings behind it. The rate of new runs has been substantial since the tooling stabilized, and the queue is growing faster than the publication pace.
