+Professionalizing dissident scientist networks within scientific self-governance is essential for legitimizing similar career paths, as such last-resort has often been assumed to reflect unprofessional conduct rather than raise concerns re. institutionalized authoritarianism. Fingers crossed, U.S.

How do the ultra-wealthy restock during the programmed recession? How do they acquire liquidity in the context of bailouts? The problem is that not everyone sees it, and we need to be well informedwhen the bailouts begin.
Maybe everyone can see it now, but the world's richest people have tanked it all to restock assets and get liquid after years of illegally playing with funny money. They used "the wokeness" as a cudgel and it worked. The next Disney princess WILL be white, as we all eat beans under the highway.
💯—Except that Research is not an Industry, is a resource. Without regulation, Journals do what anyone would do with a free resource: Profit. It’s time to stop holding journals/editors accountable whose jobs are to be profitable, and begin making policy makers accountable—whose jobs are to regulate.
“Imagine if a book publisher demanded that authors write books for free and, instead of employing in-house editors, relied on other authors to edit those books, also for free. And not only that: The final product was then sold at prohibitively expensive prices”
“Every industry has certain problems universally acknowledged as broken: In academia, it’s publishing. Academic publishing is dominated by for-profit giants like Elsevier and Springer. Calling their practice a form of thuggery isn’t so much an insult as an economic observation.”
The corresp. 1969 piece is a brilliant account of experimental physics & highlights tenacity as a key quality for scientists iopscience.iop.org/article/10.1... (Though I ignore whether being laughed at by teachers is a rite of passage for all scientists or just those in sci. underdev. environments)

Curious how this graph will look like in 4 years www.nature.com/articles/d41...
@johncarlosbaez arguments are specially relevant this week. One cannot help but wonder if the whole US Tech and @bluesky will eventually share a scorched-earth mindset to progress. Any tips on how to use @Mastodon efficiently, starting with how to follow across servers?
My heartfelt condolences to family and friends
Truly heartbroken by the passing of my dear colleague, Rudi. For a time, it felt like we were the only two intl. physics faculty in Beijing, and I am at a complete loss…
Sadly, Prof. Rudi Podgornik unexpectedly passed away ias.tau.ac.il/rudolph_podg... I still have his comments about possible effects of charge regulation on my last works and the collaboration he proposed over my desk. A big loss for our SoftMatter theory scientific community.
IAS mourns the passing of Distinguished Guest Professor Rudolf Podgornik

Thank you MK, for being an inspiring mentor and supporting my applications. I would've loved to have more opportunities to discuss—alas, time goes by unjustly fast. My condolences, dear Marci and family.
The Nobel Prize-winning chemist, Martin Karplus, has passed away. A pioneer in the theory and computation of the dynamics of macromolecules. 🧪 #ChemSky
What about experiments? We haven't been able to fund experiments in this direction, so progress is slow, but we hope to catch a break! If you liked this story stayed tuned for more spin-chain logic arxiv.org/abs/2407.20996 & (super)conductivity www.nature.com/articles/s41... stories next year! 7/7
Bc single ligands in axial-coordination lattices can be manipulated by STM to pattern circuitry, our next step is to simulate fully-atomistic phonon circuitry together with the thermal memory and a logic gate. Logic operations will be holonomic arxiv.org/abs/2411.15038, a story for another time...
Geometric phase and holonomy in the space of 2-by-2 symmetric operators
We present a non-trivial metric tensor field on the space of 2-by-2 real-valued, symmetric matrices whose Levi-Civita connection renders frames of eigenvectors parallel. This results in fundamental re...

Experimentally, we introduced similar (axial-coordination) chiral lattices on metal surfaces in 2020, with the aim to decouple substrate phonons from the molecular phonons at low temperatures. On-going experiments appears to confirm this. 5/n pubs.acs.org/doi/abs/10.1...
Our latest work strengthens the evidence that chiral lattices are platforms for the realisation of atomic-scale thermal diodes #thermodiode. It also argues that not all phonon modes express thermal nonreciprocity, hinting at the poss. of topological origins 4/n www.nature.com/articles/s41...
A thermal diode would let heat flow from A–>B but not B–>A. It'd allow reading thermal memories at specific temperatures. In 2019 we simulated the thermal excitation of a single molecule on a #chiral supramolecular lattice, evidencing transient thermal unidirectionality pubs.acs.org/doi/abs/10.1...
A specific device element is needed to leverage such thermal memory for thermodynamic circuitry–The thermal diode. The boundary states of topological vibrational phases of matter offer a strategy for the realisation of phonon diodes 2/n journals.aps.org/prb/abstract... pubs.acs.org/doi/abs/10.1...
Our latest www.nature.com/articles/s41... marks piece no. 8 since our first NC piece 9y ago www.nature.com/articles/nco... –Therein we proposed that a molecule trapped in a 2D MOF pore could function as a thermal memory at the atomic scale–the smallest container storing thermodynamic states 1/n
What about experiments? We have not been able to fund experiments in this direction, so progress is slow, but we hope to get lucky soon! If you liked this story stayed tuned for spin-chain logic arxiv.org/abs/2407.20996 and (super)conductivity www.nature.com/articles/s41... stories up next. 7/7
