Within three months, both Prof. Rodney Baxter and Prof. C. N. Yang have passed away. We have lost two founding fathers of quantum integrability. We are now living in the post-Yang-Baxter era.
I’m shocked to learn that Rodney Baxter sadly passed away. I had the honour to meet him in person in 2017 and it was a jolly memory when he ran into the wine section at the reception to grab 2 glasses of wine (his wife refused the offer and he drank both). RIP
@yujitach In the context of Japanese, パンツ refers to the underwear, right? As far as I understand, “pair of pants” doesn’t just refer to the underwear but any trousers. I might be wrong though.
I’m very sad to learn that Prof. Assa Auerbach passed away. I vividly remembered reading his textbook on magnetism during my master study. I have never met him in person but I did purchased his comic book with his encouraging words signed.

@mtbatchelor This looks amazing. One of my favourite proofs is Kuperberg's proof of ASM conjecture. Will you be joining the conference? I hope that I could by then.
I didn’t know this but apparently the author of the first paper mentioned XXZ spin chain (https://t.co/kNUrLSbtx2) in 1958 is R. Orbach, who was the under secretary of Energy under Bush administration and wrote a paper today in arXiv with Giorgio Parisi on spin glass!
@mtbatchelor That is a pity. It is sad to see that the “Leiden school of stat phys” is becoming history. The silver lining is that the Dutch school is prosperous in Australia
Occasionally in mathematics a statement that just has to be true turns out to be false. A paper appeared on arXiv today that disproves a well-known conjecture in probability called the bunkbed conjecture. 🧵

@takasan_san_san Steve Simon’s Oxford Solid State Basic did not start with tight-binding, but indeed contains those basic toy models etc. Maybe it is too “basic” to some extent
100 years ago (8 Dec. 1924), Ising submitted his renowned paper on 1-d Ising model. 80 years ago (1 Feb. 1944) Onsager’s exact solution to 2-d Ising model was published.
@takasan_san_san No worries. In general models with catogorical symmetries are not integrable. But the integrable ones satisfy YBE (they are usually RSOS-type models). Maybe we can chat about that later at Hongo :)
