Sick result: a computationally uncomputable phase diagram. Such a simple construction.

“…no general algorithm exists to determine the phase diagrams even under the promise that the phase diagram is exceedingly simple.”

Really fun collaboration with Antoine Browaeys' group (https://t.co/FPhbz0Jv6e), who made this all real. arXiv preprint at: https://t.co/BvqRC9BcT0

First paper of my PhD published: 2d quantum XY magnets with 100 Rydberg atoms!
The XY ferromagnet overcomes Hohenberg-Mermin-Wagner constraints by way of long-range dipolar interactions. Negative-temperature tricks let us see the XY antiferromagnet too. And other goodies...

@boundstate hmm I think I get what you mean. maybe Ori then? could go farther back to like, DK country, yoshi's island, crash bandicoot. somehow chrono trigger feels like this to me too

トポロジカル秩序相の基本的性質に関する論文をarXivに載せました。
先日発売の拙著「量子多体系の対称性とトポロジー」の執筆過程で疑問が生じ、アメリカの友人数名にメールで質問したことがきっかけで今回の共同研究が生まれました。
以下に内容を要約します。

The quantum Fourier transform is an MPO of bond dimension of approximately 8: https://t.co/GqWDvYy1WF (if you classically reverse the output bits). This was observed in 2014, but we give detailed arguments why, then use it to classically compute "superfast" Fourier transforms.

[Marcus Bintz @spurious_bows]

@MStoudenmire @FlatironCCQ Is there any sense in which the MPO approaches an iMPO as n->\infty?

@nick_farina I vote we go the astronomy route and have the Very Large Quantum Computer (VLCQ), Extremely Large QC (ELQC), Overwhelmingly Large QC (OLQC)

@omrilesser @DeVlugtIsaac You can still have geometric frustration by taking e.g. a triangular lattice, which can lead to interesting physics.

But you likely can't simulate phases of matter conjectured to have 'intrinsic sign problems' : topological order w/ chiral central charge, or non-abelian anyons

My alter ego Crackpotus Notorius wrote a paper on how to write papers. Since it got rejected from @viXra, I'm posting it here for now.

If you know any unusual paper that is not part of my collection, please let me know.

理論物理/数理物理では対称性が重要で、対称性といえば群、と習いますが、最近は群を含むもっと拡張された概念を対称性として考えることが行われており、空間1次元時間1次元系だとユニタリ融合圏(
