High-Pressure Structural Evolution of Na2ZrSi2O7 and Na2ZrSi2O7.H2O: Topology-Driven Compression Behaviors, Phase Stability, and Electronic Transitions
Peijie Zhang, Pablo Botella, Neha Bura +6
Silicate frameworks exhibit diverse structural responses under extreme conditions, which are strongly influenced by hydration. Here, we present a comparative high-pressure synchrot…
Emergent giant topological Hall effect in twisted Fe3GeTe2 metallic system
Hyuncheol Kim, Kai-Xuan Zhang, Yu-Hang Li +3
The topological Hall effect, driven by the exchange interaction between conduction electrons and topological magnetic textures such as skyrmions, is a powerful probe for investigat…
Coalescence of multiple topological orders in quasi-one-dimensional bismuth halide chains
Jingyuan Zhong, Ming Yang, Wenxuan Zhao +14
Topology is being widely adopted to understand and to categorize quantum matter in modern physics. The nexus of topology orders, which engenders distinct quantum phases with benefi…
Room-temperature sub-100 nm Néel-type skyrmions in non-stoichiometric van der Waals ferromagnet with ultrafast laser writability
Zefang Li, Huai Zhang, Guanqi Li +15
Realizing room-temperature magnetic skyrmions in two-dimensional van der Waals ferromagnets offers unparalleled prospects for future spintronic applications. However, due to the in…
Parity-breaking in single-element phases: Ferroelectric-like elemental polar metals
Hu Zhang, Bei Deng, Wei-Chao Wang +1
Polar metals based on binary and ternary compounds have been demonstrated in literature. Here, we propose a design principle for ferroelectric-like elemental polar metals and relat…
Negative linear compressibility and unusual dynamic behaviors of NaB3
Xin-Ling He, Shu-Ning Pan, Yue Chen +7
First-principles calculations reveal that sodium boride (NaB3) undergoes a phase transition from a tetragonal P4/mbm phase to an orthorhombic Pbam phase at about 16 GPa, accompanie…
