I'm trying to build a quantum computer in sunny Los Angeles, CA, USA.
I like discussing other people's research papers and ideas. As always, any insights should be credited to the authors themselves, and any misconceptions to me alone.

As a physics journalist, it is fairly wild to see the names of the PIs with terminated grants: Misha Lukin, Philip Kim, Lisa Randall, Subir Sachdev, John Doyle...

Paper: journals.aps.org/prl/abstract...
See also the nice writeup from Physics mag: physics.aps.org/articles/v18...

Makes sense- thanks for the context!

Neat! Something that's never been clear to me about this line of classical time crystal work: to what extent do you see it as a genuinely new thing versus more of a (valuable) reinterpretation or reassessment of older work on, e.g., nonlinear driven classical systems?

Anderson localization is an especially fertile subject for these jumps. My first paper was a minor contribution to the subject, aimed at experiments with Bose-Einstein condensates. Its most recent citation applies the ideas to suggest a better EM shield using polymers with embedded nanoparticles.

The "Popular with friends" feed is also a good middle ground.

(For physicists this will be nothing new, but feel free to keep it on hand for the next time a relative asks you about these types of announcement)

Chetan Nayak, in a comment on Scott Aaronson's blog, clarifies that this is the case and gives some details that I don't think were previously shared (that they see Z flips on a 10 ms timescale and X flips on a 5 us timescale). His March meeting talk should be interesting. scottaaronson.blog?p=8669

This is a nice piece. Strangely, even at Kusch's (and my) alma mater, the U of Illinois, there is next to nothing to memorialize him.

Meanwhile on ~~other sites~~ it has been funny to read comments accusing him of sticking his knife in the industry, betraying his own quantum team, and so on. I think one could reasonably call his take either optimistic or realistic-- but it's certainly not crazy!

Someone should write a review paper that walks through this back-and-forth! It would be a great service to the community.

Ok, one more from the condensed matter world: the Mermin-Wagner theorem prevents spontaneous breaking of continuous symmetries in 2d (and below). In practice, that means no ordered materials of certain types in a flat universe, like magnets and superconductors.

I'm not sure what the consequences would be in practice, but in 2d all conducting materials would be unstable to Anderson localization with infinitesimal disorder as well (see, e.g., www.nature.com/articles/s41...)

Hi Alex! Great suggestion, thanks!

Very interesting!
