The electrical transport of intrinsic two-dimensional ferroelectric metal PtBi2
Dan Li, Liu Yang, Lei Li
Breaking the conventional stereotype that ferroelectrics are necessarily insulating, two-dimensional (2D) ferroelectric metals combine seemingly incompatible switchable electric po…
Fractional Spin Ferroelectric and Sliding Spin Current in Magnetic Sliding Ferroelectrics
Yilin Han, Lei Li, Chaoxi Cui +3
We investigate the fractional spin ferroelectric (FSFE) in magnetic sliding ferroelectrics (SFEs), where ferroelectric switching is characterized not only by the reversal of the ou…
Unconventional Magnetism: Symmetry Classification, Hybrid-parity and Unconstrained-parity Classes
Xun-Jiang Luo, Dan Li, Rui-Chun Xiao +4
Unconventional magnetism has emerged as a transformative frontier in condensed matter physics. Such phases are characterized by substantial non-relativistic spin splitting (NSS) in…
Manipulating Anomalous Transport via Crystal Symmetry in 2D Altermagnets
Dan Li, Shuaiyu Wang, Jiabin chen +7
Anomalous transports, including the anomalous Hall effect (AHE) and anomalous Nernst effect (ANE), are typical manifestations of time-reversal-symmetry-breaking responses in materi…
Ferroelectrically Controlled Chirality Switching of Weyl Quasiparticles
Zeling Li, Yu liu, Le Du +6
Weyl quasiparticles, as gapless low-energy excitations with nontrivial chirality, have garnered extensive interest in recent years. However, archieving effective and reversible con…
Floquet control of topological phases and Hall effects in Z2 nodal line semimetals
Pu Liu, Chaoxi Cui, Lei Li +3
Dynamic control of topological properties in materials is central to modern condensed matter physics, and Floquet engineering, utilizing periodic light fields, provides a promising…
