Atomic Physics (Past & Present)

@philipcball Naïvely, I used to believe that. Then I delved more into it, and learned the contributions of Leon Lederman on parity violation.

@quantumcascade It’s about time they gave you your medal. Good luck!

I am honored to be included in this list and I am grateful to the many students, postdocs and colleagues that have collaborated with me; without you it wouldn’t have happened! clarivate.com/news/clarivate…

This is what happens when we (over?) step into a field without spending enough time to understand it properly.

@martinmbauer Two points: 1. By your reasoning: Science will always be, as it always has been, since the ‘experts’ are always right. 2. You resorted to ‘reductio ad absurdum’-ism. That guys was pretending to promote ‘reasoned questioning’, while you focused on ‘consensus’. Good luck.

You can question science. But people often don’t understand how scientific consensus is formed. The one paper contradicting the consensus is likely a statistical outlier. And the contrarian that proves all experts wrong is likely just a narcissist not willing to admit being wrong

@culturaltutor @threadreaderapp unroll

And that's why the hands of a clock rotate in the direction they do. So, other than geography, it did have something to do with time - clocks were invented in the Northern Hemisphere first and the relevant sundial layout was adopted.

Why do clocks move in that direction?! (It's got nothing to do with time...)

"On the theory of Superfluidity" What a beautiful exchange between Landau and Tisza! One criticises the other, while appreciating each other's insights. Wonderful read at: journals.aps.org/pr/pdf/10.1103… journals.aps.org/pr/pdf/10.1103…

Beautiful work by Peter Schauss and colleagues. "Quantum gas microscopy of a geometrically frustrated Hubbard system" arxiv.org/abs/2210.14895

@PhysRevLett End of an era.

Editorial: A Welcoming Home for Applied Science With new journals, special content, and a broad outreach effort, the Physical Review journals aim to be a leader in publishing applied research. e.g., PRL's recently modified acceptance criteria journals.aps.org/prl/2022/10/11…

Fantastic work by Markus Greiner and colleagues. FQHE with cold atoms, finally! "Realization of a fractional quantum Hall state with ultracold atoms" arxiv.org/abs/2210.10919

@stevenstrogatz Extremely creative and beautiful article. I liked your humility in the conclusion --- "As we have tried to show in this article ... " : )

This image shows one of the equipotential surfaces around a uniformly charged trefoil. A big question (currently unsolved) is: What's the minimum number of zeros (equilibrium points) in the electric field around a given charged knot, as we deform the knot without untying it?

In a new paper with my student Max Lipton @Maxematician and colleague Alex Townsend, we looked at the electric field around charged loops in 2D and knots in 3D. Found some surprises and raised lots of new questions and conjectures. The topic is wide open! journals.aps.org/prresearch/abs…

Wonderful work by Jörg Schmiedmayer and colleagues. Simulation of QFT with ultracold atoms. "Experimental Observation of Curved Light-Cones in a Quantum Field Simulator" arxiv.org/abs/2209.09132

@stevenstrogatz Thank you!

@AtomicUpdates Saff and Snider, fundamentals of complex analysis, third edition

I'm traveling this week, so I pre-recorded a couple of complex analysis lectures for my students. Some of you might find them interesting (they depend on three weeks of prior material, but might be understandable anyway). I'll post the links in the next 3 tweets in this thread.
