铁电动力学及其在物理与化学中的应用
Ferroelectricity, characterized by reversible electric polarization under an external electric field, has long served as a cornerstone for non-volatile electronics and digital information storage technologies. In this talk, I will present our recent advances in understanding ferroelectric domain formation, polarization switching, and dynamic stability in low-dimensional ferroelectric materials through the integration of density functional theory (DFT), machine learning potentials, and deep learning molecular dynamics (DLMD) simulations. Beyond physical functionalities, I will also discuss how ferroelectric polarization can be exploited to regulate chemical reactions and energy conversion processes. Our recent studies highlight the critical role of switchable polarization in tailoring surface charge redistribution and interfacial electronic structures, thereby modulating reaction pathways and catalytic efficiencies in key systems, including photocatalytic water splitting, electrocatalytic CO₂ reduction, and nitrogen reduction reactions.

Vertex-primitive s-arc-transitive Cayley digraphs
Determining an upper bound on s for vertex-primitive s-arc-transitive digraphs has been an open problem of considerable interest since a question asked by Praeger in 1990. Although much progress has been made and an upper bound is conjectured to be 2, a complete classification for s=2 remains out of reach. In this paper, we prove that the tight upper bound on s for finite vertex-primitive s-arc-transitive Cayley digraphs is exactly 2. Furthermore, we completely characterize the structure of these digraphs when s=2.

Chiral charge density waves in Janus monolayer
Spontaneous symmetry breaking and emergent electronic order have been widely discussed in condensed matter physics, providing a general framework for understanding complex phase transitions in quantum materials. Layered transition-metal dichalcogenides host a particularly rich variety of charge density wave states, which often compete or coexist with superconductivity. Here, using first-principles calculations, we propose that CDW instabilities are broadly realized in 1T Janus TMD monolayers. The condensation of CDW modes removes the remaining mirror symmetry of polar Janus lattice, giving rise to a threefold polar chiral phase. Momentum-resolved electron-phonon coupling and bare Lindhard susceptibility reveal distinct microscopic characteristics across the different CDW families. These results establish Janus monolayer as a versatile playground for exploring the interplay among chirality, electronic orders, and quantum phase transitions.
