Intertwined Topological Phases in TaAs2 Nanowires with Giant Magnetoresistance and Quantum Coherent Surface Transport

Advanced Materials, EarlyView.
Synthesis of topological semimetal TaAs2 nanowires in situ encapsulated with a thin SiO2 shell unravel a richness of intertwined topological phases manifested by their magnetotransport features: A near‐room‐temperature metal‐to‐insulator transition, strong expressions of topologically nontrivial surface transport, giant magnetoresistance with direction‐

CurvGAD: Leveraging Curvature for Enhanced Graph Anomaly Detection [PDF]

arXiv
Does the intrinsic curvature of complex networks hold the key to unveiling graph anomalies that conventional approaches overlook? Reconstruction-based graph anomaly detection (GAD) methods overlook such geometric outliers, focusing only on structural and attribute-level anomalies.

Recent Advances in Wide‐Bandgap Perovskite Solar Cells

Advanced Materials, EarlyView.
Ubiquitous defects predominately account for photo‐instability and open‐circuit voltage losses in wide‐bandgap perovskite solar cells (WBG PSCs). This review comprehensively presents the underlying impact mechanisms, summarizes the advanced optimization strategies across various functional layers and their interfaces to develop efficient and stable WBG

Anomaly of subsystem symmetries in exotic and foliated BF theories

Journal of High Energy Physics
We study the mixed ’t Hooft anomaly of the subsystem symmetries in the exotic BF theory and the foliated BF theory in 2+1 dimensions, both of which are fractonic quantum field theories describing the equivalent physics.

Inorganic Dielectric Materials Coupling Micro‐/Nanoarchitectures for State‐of‐the‐Art Biomechanical‐to‐Electrical Energy Conversion Devices

Advanced Materials, EarlyView.
Biomechanical‐to‐electrical energy conversion devices are uniquely suited for self‐driven physiological information monitoring and powering human–computer interaction systems. These devices based on micro‐/nanoarchitectured inorganic dielectric materials (MNIDMs) have shown ultrahigh electromechanical performance and thus great potential for practical ...

Fermion masses and flavor mixings and strong CP problem

Nuclear Physics B, 2019
For all the success of the Standard Model (SM), it is on the verge of being surpassed. In this regard we argue, by showing a minimal flavor-structured model based on the non-Abelian discrete SL2(F3) symmetry, that U(1) mixed-gravitational anomaly ...

Non‐Hermitian Boundary in a Surface Selective Reconstructed Magnetic Weyl Semimetal

Advanced Materials, Volume 37, Issue 14, April 9, 2025.
This study is the first to propose that the surface reconstruction of a Weyl semimetal creates a Hermitian bulk‐non‐Hermitian boundary system. The non‐Hermitian effects arising from the surface reconstruction are manifested by the emergence of non‐topological surface Fermi arcs (NTSFAs) and the broadening of both topological surface Fermi arcs (SFAs ...
