Critically Enhanced Magnon Transport in Low-dimensional Magnets
Ping Tang
Transport properties of (quasi)particles in condensed matter depend profoundly on the spatial dimension. Motivated by recent advances in growing ultrathin magnetic films and monola…
Thermoelectric response of a ferroelectric insulator
Ryo Iguchi, Takashi Teranishi, Sakyo Hirose +4
Thermoelectric effects enable the conversion between heat and electricity without moving parts. While conventionally associated with mobile charges, we report thermoelectricity cau…
Spin-caloritronic signatures of soft magnons in bilayer CrSBr
Rob den Teuling, Ping Tang, Gerrit E. W. Bauer +1
Spin transport in magnetic insulators is often treated by assuming that magnons carry a fixed spin angular momentum of , which does not hold in general, however. Here we cal…
Absence of Quantum-Metric-Induced Intrinsic Longitudinal Response
Ping Tang
Nonlinear charge transport in solids has emerged as a powerful probe of the quantum geometric properties of Bloch electrons. While the Berry curvature underlies the intrinsic anoma…
Emergence of Nontrivial Topological Magnon States in Skyrmionium Lattices with Zero Topological Charge
Xingen Zheng, Ping Tang, Xuejuan Liu +3
We predict the emergence of nontrivial topological magnon states in the skyrmionium lattice with zero topological charge. We propose the concept of weighted magnetic flux, which pr…
Multiferroic-like Quasiparticles in Ferroelectrics
Ping Tang, Gerrit E. W. Bauer
Multiferroics are materials with coexisting electric and magnetic orders that are of central importance for fundamental research and technological applications. Unfortunately, intr…
