Superconductors, orbital magnets and correlated states in magic-angle bilayer graphene [PDF]

Nature, 2019
Superconductivity can occur under conditions approaching broken-symmetry parent states1. In bilayer graphene, the twisting of one layer with respect to the other at ‘magic’ twist angles of around 1 degree leads to the emergence of ultra-flat moiré ...

Multi-kingdom gut microbiota analyses define COVID-19 severity and post-acute COVID-19 syndrome

Nature Communications, 2022
Here, by performing an integrative multi-omics analysis coupled to clinical features of COVID-19 patients prospectively followed for up to 6 month, the authors identify specific gut microbiome patterns associated with disease severity and development of ...

"Magic Chloro": Profound Effects of the Chlorine Atom in Drug Discovery.

Journal of Medicinal Chemistry, 2023
Chlorine is one of the most common atoms present in small-molecule drugs beyond carbon, hydrogen, nitrogen, and oxygen. There are currently more than 250 FDA-approved chlorine-containing drugs, yet the beneficial effect of the chloro substituent has not ...

Electric field–tunable superconductivity in alternating-twist magic-angle trilayer graphene

Science, 2021
A twisty trilayer The discovery of superconductivity in bilayers consisting of graphene sheets twisted with respect to each other by just the right “magic” angle has inspired enormous interest in twisted materials. Hao et al. constructed twisted trilayer

Symmetry-broken Josephson junctions and superconducting diodes in magic-angle twisted bilayer graphene

Nature Communications, 2023
Correlated electronic states in moiré matter are of great fundamental and technological interest. Here, the authors demonstrate a Josephson junction in magic-angle twisted bilayer graphene with a correlated insulator weak link, showing magnetism and ...

Magic-angle helical trilayer graphene [PDF]

Science Advances, 2023
We propose magic-angle helical trilayer graphene (HTG), a helical structure featuring identical rotation angles between three consecutive layers of graphene, as a unique and experimentally accessible platform for realizing exotic correlated topological ...

Nematicity and competing orders in superconducting magic-angle graphene [PDF]

Science, 2020
Twisted and nematic Electrons in quantum materials can break rotational symmetry even when the underlying crystal lattice does not. This phenomenon, called nematicity, has been observed in many unconventional superconductors. Cao et al.
