Or, forgive the double-pun, maybe it’s nontrivial (product space) after all 😆

+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.

💯—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”

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)

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...
