On the origin of in-gap states in amorphous Ge2_2Sb2_2Te5_5

By combining machine learning interatomic potentials with hybrid density functional theory, this study identifies that in-gap states in amorphous Ge2_2Sb2_2Te5_5 primarily arise from structural defects like wrong bonds and specific coordination anomalies, which are depleted during glass aging to explain the mechanism of resistance drift in phase change memory devices.

Hydrostatic Pressure-enhanced correlated magnetism and Chern insulator in moir'e WSe2

This study demonstrates that hydrostatic pressure, applied via a cryogenic dual-gated diamond-anvil platform, continuously enhances moiré potentials in twisted bilayer WSe2 to stabilize Stoner ferromagnetism and strengthen Chern insulating states, while also driving a topological phase transition from a Chern insulator to a Mott insulator through a pressure-induced valence-band switching mechanism.

Electric-field-tuned consecutive topological phase transitions between distinct correlated insulators in moire MoTe2/WSe2 heterobilayer

This study reports the experimental observation of two consecutive electric-field-driven topological phase transitions in MoTe2/WSe2 moire heterobilayers, where the system evolves from a geometrically frustrated Mott insulator to a ferromagnetic quantum anomalous Hall state and finally to an antiferromagnetic valley-coherent insulator, demonstrating a tunable platform for correlation-topology intertwined physics.
