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

Do you love https://t.co/nqxW8sac9d like me and wish you don't have to wait for a month before you can read arXiv submissions right in your browser? Here's a Telegram bot that runs ar5iv conversions on demand using the official docker image:

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.

Two interesting preprints on Majorana zero modes in interacting systems appeared this week. Happy to see this activity in the field!

[Omri Lesser @omrilesser]

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.

[Omri Lesser @omrilesser]

Interesting take by @AkhmerovAnton on the recent Microsoft Majorana preprint

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
