I'm pleased to have finished this simple note with Gabe Waite (@quantumbeef_) on efficient algorithms for weakly-interacting quantum spin systems at arbitrary temperature.

I'm excited to share that my new website, Scift (https://t.co/EY8fKmow9T), is now live!

Scift is a simple way to explore scientific preprints from across all areas of science — no ratings, no comments, just the papers to read and consider on your own terms.

[Ryan Mann @ryanlmann]

Key features:
– Explore new science as it is posted.
– Save papers to your profile to revisit anytime.
– Meet your Scibling: after enough activity, Scift will match you with another scientist around the world who shares your research interests.

Very sad that Yle Kielikoulu is shutting down. It's one of the most important resources for learning Finnish. #pelastaylekielikoulu #saveylekielikoulu #saveylespråkskolan @yle @lvmfi

I'm pleased our paper on a graph-theoretic framework for free-parafermion solvability has been published in RSPA. We prove that if the frustration graph of a spin system is an oriented indifference graph, then it has an exact free-parafermion solution. https://t.co/lBzQ1jHuW3

Gabe Waite (@quantumbeef_) of the Hamiltonian Jungle has uploaded his first first-author paper: "The Complexity of Local Stoquastic Hamiltonians on 2D Lattices". Read here: https://t.co/Km5TlZd8CR

[Ryan Mann @ryanlmann]

I'm pleased that our work on the optimal scheduling of graph states via path decompositions has been published in Physical Review A. https://t.co/RoRfN7SMQ5

[Ryan Mann @ryanlmann]

New paper with Samuel Elman, David Wood, and Adrian Chapman! We provide a graph-theoretic characterisation of when a quantum spin system can be solved via a mapping to free parafermions.

The Hamiltonian Jungle has expanded! In our latest update we unravel the secrets of Cluster Expansions, C*-Algebras, and MCMC. We also explore the complexities of Stoquastic Hamiltonians and Partition Functions.

Explore the jungle at https://t.co/oC7hOIM21y!

@ccanonne_ Yes! Christmas is early next year!

[Ryan Mann @ryanlmann]

On the arXiv today, Sam, Jason, and me,
Posted some trivial results on MBQC.

@HyperboIeva Gabe Waite did most of the hard work.

[Ryan Mann @ryanlmann]

A special thanks to Gabe Waite for his relentless hard work and dedication. Feel free to contact us at [email protected] with suggestions or enquiries.

The Hamiltonian Jungle is now alive! Inspired by the legacy of the Complexity Zoo, Quantum Algorithm Zoo, and Error Correction Zoo, this new website categorises the complexities of local Hamiltonian problems. Explore the jungle at https://t.co/oC7hOIM21y.

[Ryan Mann @ryanlmann]

I'm delighted that our paper on algorithmic cluster expansions for quantum problems, authored with @rminkomaths, has been accepted for publication in PRX Quantum.
