Gate-Tunable Ambipolar Josephson Current in a Topological Insulator

This study demonstrates gate-tunable ambipolar Josephson current in molecular beam epitaxy-grown bulk-insulating (Bi,Sb)₂Te₃ thin films, revealing distinct transport behaviors between thin and thick films and establishing a critical foundation for realizing Dirac-surface-state-mediated topological superconductivity and Majorana modes.

Orbital Hybridization-Induced Ising-Type Superconductivity in a Confined Gallium Layer

This study demonstrates that a plasma-free, carbon buffer-assisted epitaxial method can synthesize air-stable graphene/trilayer gallium/SiC heterostructures exhibiting Ising-type superconductivity, where interfacial orbital hybridization induces spin-split Fermi surfaces and an in-plane upper critical magnetic field that significantly exceeds the Pauli paramagnetic limit.

The fate of disorder in twisted bilayer graphene near the magic angle

This study reveals that in magic-angle twisted bilayer graphene, moderate disorder paradoxically enhances conductance by inducing delocalization before stronger disorder restores localization, a unique behavior driven by flat-band physics that distinguishes it from large-angle systems and offers insights into fractional quantum anomalous Hall effects.

Weak localization and universal conductance fluctuations in large area twisted bilayer graphene

This paper reports the first observation of weak localization in large-area twisted bilayer graphene across various twist angles and identifies signatures of universal conductance fluctuations in high-mobility samples near a van Hove singularity.

Probing spatially resolved spin density correlations with trapped excitons

This paper proposes a method to probe spatially resolved electron spin density correlations in atomically thin van der Waals materials by utilizing trapped excitons in a moiré lattice as an optical probe that detects energy shifts mediated by electron-exciton scattering, thereby enabling the characterization of quantum phase transitions and superconducting pairing symmetries.
