We present a systematic theory of acoustic-phonon-mediated superconductivity, which incorporates Coulomb repulsion, explaining the recent experiment in Bernal bilayer graphene under a large displacement field. The acoustic-phonon mechanism predicts that s-wave spin-singlet and f -wave spin-triplet pairings are degenerate and dominant. Assuming a spin-polarized valleyunpolarized normal state, we obtain f -wave spin-triplet superconductivity with a Tc ∼ 20 mK near ne = −0.6 × 10 cm−2 for hole…

Isospin magnetism and spin-polarized superconductivity in Bernal bilayer graphene
In conventional superconductors, Cooper pairing occurs between electrons of opposite spin. We observe spin-polarized superconductivity in Bernal bilayer graphene when doped to a saddle-point van Hove

Electric field–tunable superconductivity in alternating-twist magic-angle trilayer graphene
TLDR
By tuning the doping level and displacement field, it is found that superconducting regimes occur in conjunction with flavor polarization of moiré bands and are bounded by a van Hove singularity at high displacement fields.
Flavour Hund's coupling, Chern gaps and charge diffusivity in moiré graphene.
TLDR
This work investigates the broken-symmetry many-body ground state of magic-angle twisted bilayer graphene (MATBG) and its nontrivial topology using simultaneous thermodynamic and transport measurements and directly observes flavour symmetry breaking as pinning of the chemical potential at all integer fillings of the moiré superlattice.
