Isospin magnetism and spin-polarized superconductivity in Bernal bilayer graphene

Haoxin Zhou et al.

Summary: Spin-polarized superconductivity is observed in Bernal bilayer graphene under a large applied perpendicular electric field. Electrostatic gate tuning leads to transitions between electronic phases with different polarizations in the spin space. A transition to a superconducting state is observed at a finite magnetic field, and the critical temperature is consistent with a spin-triplet order parameter.

Cascade of isospin phase transitions in Bernal-stacked bilayer graphene at zero magnetic field

Sergio C. de la Barrera et al.

Summary: This study demonstrates the existence of a cascade of symmetry-broken states with spontaneous spin and valley isospin ordering in bilayer graphene at zero magnetic field. These states are intrinsic to natural graphene bilayers and can be explored by independently tuning the carrier density and electric displacement field.

Robust superconductivity in magic-angle multilayer graphene family

Jeong Min Park et al.

Summary: Superconductivity has been observed in magic-angle twisted four-layer and five-layer graphene systems, expanding the family of moire superconductors. The distinction between the twisted bilayer graphene and other members of the family is related to the movement of electrons between layers in a magnetic field. This discovery provides new insights for the design of superconducting materials platforms.

Pairing symmetry of twisted bilayer graphene: A phenomenological synthesis

Ethan Lake et al.

Summary: In this study, the nature of the superconducting phase in twisted bilayer graphene is investigated through a comprehensive synthesis of existing experiments. The paper argues that experimental constraints are strong enough to determine the structure of the superconducting order parameter, which is found to be nodal and composed of a mixture of spin-singlet and spin-triplet Cooper pairs. The orbital parity of the order parameter, however, remains unknown and could either be p wave or d wave. A proposed method for distinguishing between the two is discussed using the measurement of Andreev edge states.

Acoustic-phonon-mediated superconductivity in Bernal bilayer graphene

Yang-Zhi Chou et al.

Summary: This article presents a systematic theory of acoustic-phonon-mediated superconductivity that incorporates Coulomb repulsion and explains recent experiments in Bernal bilayer graphene. The theory predicts that s-wave spin-singlet and f-wave spin-triplet pairings are degenerate and dominant. The results indicate that the observed spin-triplet superconductivity in Bernal bilayer graphene arises from acoustic phonons.

Counterintuitive gate dependence of weak antilocalization in bilayer graphene/WSe2 heterostructures

Julia Amann et al.

Summary: This research investigates spin-orbit coupling in bilayer graphene/transition metal dichalcogenide heterostructures, and finds that the visibility of weak antilocalization effect does not necessarily increase with the increase of spin-orbit splitting under certain conditions. This phenomenon is caused by the intricate dependence of spin lifetimes on symmetric and antisymmetric spin lifetimes.

Unconventional Superconductivity in Systems with Annular Fermi Surfaces: Application to Rhombohedral Trilayer Graphene

Areg Ghazaryan et al.

Summary: In a two-dimensional electron gas with an annular Fermi surface, long-range Coulomb interactions can lead to unconventional superconductivity through the Kohn-Luttinger mechanism. Superconductivity is significantly enhanced when the inner and outer Fermi surfaces are close, with the prevailing state having chiral p-wave symmetry. These results are discussed in the context of recent discoveries of superconductivity in rhombohedral trilayer graphene with an annular Fermi surface.

Tunable strongly coupled superconductivity in magic-angle twisted trilayer graphene

Jeong Min Park et al.

Summary: Moire superlattices have become a platform for studying correlated physics and superconductivity with unprecedented tunability. This study on magic-angle twisted trilayer graphene reveals a better tunability of electronic structure and superconducting properties than magic-angle twisted bilayer graphene, with implications for the understanding of strongly coupled superconductivity. The results suggest that the system can be electrically tuned close to the crossover to a two-dimensional Bose-Einstein condensate, indicating the potential for revolutionizing applications of superconductivity.

Summary: By constructing a van der Waals heterostructure with three stacked graphene layers at alternating twist angles, researchers observed tunable superconductivity at a specific twist angle. The superconducting regions are associated with flavor polarization of moire bands and are bounded by a van Hove singularity at high displacement fields, indicating unconventional moire superconductivity.

Twist-angle dependent proximity induced spin-orbit coupling in graphene/transition metal dichalcogenide heterostructures

Thomas Naimer et al.

Summary: In this study, we investigated the proximity-induced spin-orbit coupling in heterostructures of twisted graphene and monolayers of transition metal dichalcogenides (TMDCs) MoS2, WS2, MoSe2, and WSe2 from first principles. We found that strain plays a key role in affecting the band offsets and magnitudes of the proximity couplings. The dominant, valley-Zeeman, and Rashba spin-orbit couplings were identified and their behaviors with different twist angles were analyzed.
