Symmetry-broken Josephson junctions and superconducting diodes in magic-angle twisted bilayer graphene.
Díez-Mérida et al. (2023)
This groundbreaking study on symmetry-broken Josephson junctions in magic-angle twisted bilayer graphene (MATBG) offers tantalizing possibilities for the Molecular Streaming Corps' nanopore sensing endeavors. While the MR1 currently focuses on ionic current measurements, the unique electronic properties of MATBG could inspire novel solid-state nanopore designs with unprecedented control over charge transport. The authors' demonstration of gate-tunable superconductivity and magnetism in a single material system suggests potential for dynamically adjustable nanopores, where pore conductance and selectivity could be fine-tuned in real-time. Their realization of a zero-field superconducting diode hints at possibilities for creating nanopores with directional conductance, potentially enhancing signal-to-noise ratios in molecular detection. MSC researchers might explore incorporating MATBG elements into future MR1 cartridges, leveraging its rich phase diagram to create "smart" pores that adapt to different analytes or experimental conditions. This work exemplifies the kind of cross-disciplinary innovation that could accelerate progress towards utility-scale molecular streaming.

Explain this to me like I'm a ten year old.
Imagine you have two sheets of graphene—a super thin material made of carbon atoms—and you stack them on top of each other, but with a tiny twist. When you twist them just right (at the "magic angle"), something amazing happens: the electrons in the material start behaving in really weird and cool ways! In this experiment, scientists made a special kind of switch (called a Josephson junction) using this twisted graphene. They discovered that by applying different electrical voltages, they could make parts of the graphene become superconducting (where electricity flows with zero resistance) or magnetic. The coolest part? They made a "superconducting diode"—a device that lets electricity flow easily in one direction but not the other, without needing any magnets! It's like creating a one-way street for electrons using just electricity. This discovery is super exciting because it could lead to new types of quantum computers and electronics that are faster and more efficient than anything we have today. It's like finding a new LEGO piece that lets you build things you never could before!

Hear a madman's opinion.
"Nanospores! You've done it, you mad graphene wranglers! Twisting reality itself, are we? Ha! I've seen quarks do the tango in eleven dimensions, but this—THIS is the real cosmic jest! Magic angles, they say? BAH! It's the laughter of hyperdimensional cephalopods, tickling the very fabric of spacetime with their tentacles of quantum tomfoolery! But wait! You've birthed a superconducting diode from the twisted womb of moiré patterns? Oh, the universe chuckles at your audacity! It's like teaching a black hole to hiccup unidirectionally! And what's this? Gate-tunable magnetism without so much as a 'by your leave' to Maxwell's equations? You're playing quantum hopscotch on the grave of classical physics, you beautiful lunatics! Mark my words, when the Great Nanopore in the Sky starts streaming consciousness itself, it'll be through your blasted magic-angle graphene! And just you wait—one day, you'll wake up to find your coffee mug has become a topological insulator, and your toast will refuse to burn on one side due to spontaneous time-reversal symmetry breaking! The MADNESS of it all! ...Though I must admit, a zero-field superconducting diode at 3.5 Kelvin is rather impressive from an engineering standpoint."

Come on Keltar's Talk Show to Discuss your Paper!
Twisted Bilayer Ballad (A quantum sea shanty) Oh, gather 'round, ye quanta crew, And hear the tale of graphene true! Two sheets aligned with magic twist, Where electrons dance in quantum mist! CHORUS: Yo ho, yo ho, a Josephson's life for me! Superconducting seas, so wild and free! With gates to tune and phases to shift, We'll ride the moiré waves and never drift! In Díez-Mérida's grand design, Symmetry breaks and currents align. Magnetism blooms without a field, As valley polarizations yield! CHORUS Fraunhofer's pattern, askew and bold, Hysteresis loops our tale unfold. Three Kelvin high, the effects persist, A quantum playground not to be missed! CHORUS Now heed ye well, ye streaming corps, For in these junctions lie future pores! With graphene twisted just so right, We'll stream molecules day and night! FINAL CHORUS: Yo ho, yo ho, a nano-streamer's dream! Where magic-angle pores make molecules beam! With Efetov's map and Maxine's Quest, We'll chart the seas of the quantum west!
