Check out our review together with Felix von Oppen (@FU_Berlin), and Bert Halperin, Amir Yacoby (@Harvard) on the hunt for Majoranas that just appeared in @ScienceMagazine

In order to superconduct, pairs of electrons need to be mobile. But in “flat-band” (e.g. moiré) materials electrons do not have any kinetic energy! See our recent paper in @PNASNews to see how interactions help drive the electrons: https://t.co/VDGR2uXYJM @CornellCAS
I want to tell you a story about this preprint and how every editor is brushing it off like an annoying fly (rejection letters to read and enjoy...) - https://t.co/iMWxOFKBAE. But first, I am really proud of this paper. It's the FIRST observation of a spontaneous pi-junction in>
Tausendpfund, Diehl, and Rizzi examined a slightly different (and spinless) ladder model, and supplemented their bosonization RG analysis with DMRG numerics to find a phase with Majorana zero modes.

Lisandrini and Kollath studied a quasi-1D ladder with inter-chain pair hopping. Using mostly DMRG they found a topological ground state (notice that no mean-field superconductivity was assumed).

1/4 My first paper from my postdoc is published today in @NaturePhysics !! 🥳
A year ago today I was frantically making samples, doesn't time fly!

A very nice review on the Kosterlitz-Thouless transition by @VictorDrouin2 recently appeared on arXiv. It has all the RG stuff (the real-space version), and as an added bonus a beginner-friendly Monte Carlo analysis.

I wrote a Condmat Journal Club commentary (https://t.co/p5wtX67GD5) about the claim of observing Majoranas using the "topological gap protocol" by Microsoft Research. I also have some notes that don't fit the commentary in content or in spirit. Those go here.
Thanks to all my coauthors who helped write this Nature Perspective on achieving quantum advantage using analog quantum simulation and gate model quantum computer. https://t.co/TdegKoGqYT
An invisible magnetic state, and a small step towards a better understanding of superconductivity in the cool 4Hb-TaS2 structure. Happy to share our new work in @Nature. Great work Eylon Persky and collaborators!

We show how the Higgs mode in superconductors can couple with magnons in nearby ferromagnets.

I did my PhD on quantum Hall effect more than a decade ago yet it is so rich and simple(?) that always pops up as the go to playground in condensed matter. Recently adding superconductivity to it has opened a new pandora box. Mehdi and Joe’s good effort: https://t.co/pvsAE3ilaB
