Bichargon Hall Effect
Ping Tang
The conventional Hall effect arises from the transverse deflection of mobile electronic charge carriers in conductors. Here, we predict a bosonic charge Hall effect in charge-order…
Collective Charge-\(2e\) Bosonic Excitations in Charge-Ordered Systems
Ping Tang
Charge order is conventionally characterized by a static modulation of the electronic density, while its collective excitations remain less developed from a quasiparticle perspecti…
Pseudospin Dynamics of Charge Order
Ping Tang
Charge order is conventionally viewed as a static modulation of the electronic density, despite growing experimental capabilities to probe and manipulate its nonequilibrium evoluti…
Chirality-Selective Phonon Pumping by Ferroelectric Dynamics
Dapeng Yao, Ping Tang
The discovery of chiral phonons has expanded the conventional view of lattice vibrations as passive heat carriers, opening new opportunities for phononic spintronic devices. Howeve…
Observation of nonlocal ferron-drag thermoelectricity
Takuma Itoh, Takamasa Hirai, Ping Tang +8
The Peltier effect induces a heat current when a charge current passes through a conductor. Since a charge current is conserved at the junction between two different conductors, th…
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…
Observation of ferron transport in ferroelectrics
Kaiwen Shen, Ping Tang, Xianzhe Chen +15
Ferroelectrics feature spontaneous electric dipolar order reconfigurable via electric fields. Recent theoretical studies of the collective excitations of this electric dipolar orde…
Exchange Surface Spin Waves in Type-A van der Waals Antiferromagnets
Zhoujian Sun, Fuxiang Li, Gerrit E. W. Bauer +1
Surface spin waves in the short-wavelength regime enable ultrafast, nanoscale magnon-based devices. Here we report the emergence of surface spin-wave excitations within the bulk ma…
Magnon-Driven Magnetothermal Transport in Magnetic Multilayers
Ping Tang, Ken-ichi Uchida, Gerrit E. W. Bauer
All-solid-state nanoscale devices capable of efficiently controlling a heat flow are crucial for advanced thermal management technologies. Here we predict a magnon-driven magnetoth…
Role of Disorder in the Intrinsic Orbital Hall Effect
Ping Tang, Gerrit E. W. Bauer
We investigate the effect of random defect scattering on the orbital Hall effect by solving a quantum Boltzmann equation. Depending on the specific orbital textures, diffuse scatte…
Electrical Injection and Transport of Coherent Magnons in Non-Collinear Antiferromagnets
Ping Tang, Gerrit E. W. Bauer
Non-collinear antiferromagnets (nAFMs) with a small net magnetic moment offer new opportunities for ultrafast spintronic devices, owing to unique physical properties. While in ferr…
Electric Analog of Magnons in Order-Disorder Ferroelectrics
Ping Tang, Gerrit E. W. Bauer
We analyze the ``ferron" excitations in order-disorder ferroelectrics by a microscopic pseudo-spin model. We demonstrate that analogous to magnons, the quanta of spin waves in magn…
Surface Ferron Excitations in Ferroelectrics and Their Directional Routing
Xi-Han Zhou, Chengyuan Cai, Ping Tang +4
The duality between the electric and magnetic dipoles inspires recent comparisons between ferronics and magnonics. Here we predict surface polarization waves or ``ferrons" in ferro…
