MIT physicists report the unexpected discovery of electrons forming crystalline structures in a material only billionths of a meter thick. The work adds to a gold mine of discoveries originating from the material, which the same team discovered about three years ago. In a paper published Jan. 22 in Nature(https://lnkd.in/eGN3_mdT), the team describes how electrons in devices made, in part, of the material can become solid, or form crystals, by changing the voltage applied to the devices when they are kept at a temperature similar to that of outer space. Under the same conditions, they also showed the emergence of two new electronic states that add to work they reported last year showing that electrons can split into fractions of themselves. The team also observed all of these phenomena using two slightly different “versions” of the material, one composed of five layers of atomically thin carbon; the other composed of four layers. This indicates “that there’s a family of materials where you can get this kind of behavior, which is exciting,” says Long Ju, a MIT CQE member, an assistant professor in the MIT Department of Physics who led the work. Ju is also affiliated with MIT’s Materials Research Laboratory and Research Lab of Electronics.

✨ I am pleased to share our new paper, "Superfluid Stiffness in Magic-Angle Twisted Bilayer Graphene," is now published in Nature! 🎉 In this study, we probe the superfluid stiffness of magic-angle twisted bilayer graphene (MATBG) using circuit quantum electrodynamics (cQED). By integrating MATBG into a superconducting quarter-wave resonator, we track its frequency shift as a function of Fermi energy, temperature, and bias current. This approach provides key insights into pairing symmetry and the role of quantum geometry in MATBG and other correlated superconductors. Unlike our previous work at EQuS, where we explored superconducting qubits using van der Waals materials(graphene, hBN, NbSe₂, etc.), this time we flip the script: leveraging techniques and architectures developed for superconducting qubits to "read out" fundamental quantum material properties. This work highlights the exciting synergy between quantum materials and superconducting quantum technology, opening up new avenues for discovery. There’s still so much to explore, and we’re just at the beginning!

Physicists at Massachusetts Institute of Technology and Harvard University have now directly measured superfluid stiffness for the first time in “magic-angle” graphene — materials that are made from two or more atomically thin sheets of graphene twisted with respect to each other at just the right angle to enable a host of exceptional properties, including unconventional superconductivity. This superconductivity makes magic-angle graphene a promising building block for future quantum-computing devices, but exactly how the material superconducts is not well-understood. Knowing the material’s superfluid stiffness will help scientists identify the mechanism of superconductivity in magic-angle graphene. The team’s measurements suggest that magic-angle graphene’s superconductivity is primarily governed by quantum geometry, which refers to the conceptual “shape” of quantum states that can exist in a given material. The results, which are reported in the journal Nature(https://lnkd.in/eqZ_DCGW), represent the first time scientists have directly measured superfluid stiffness in a two-dimensional material. To do so, the team developed a new experimental method which can now be used to make similar measurements of other two-dimensional superconducting materials.
