Magnetic-Field Selection of Magnetic Order in Altermagnets and Noncollinear Antiferromagnets
Qiu-Shi Huang, Chaoxi Cui, Yilin Han +3
Conventional field selection of magnetic order relies on the Zeeman coupling, which, however, vanishes in magnets without net magnetization, a rapidly growing class including alter…
Néel-order-dependent transverse transport in noncoplanar antiferromagnet
Qi Feng, Yilin Han, Yongkai Li +9
Antiferromagnets hold appealing potential in next-generation spintronic devices with higher frequency and scalability, thanks to their alternating spin orientations that cancel out…
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…
Rotation topological states: theory and material realization
Chun-Xue Liu, Yilin Han, Runze Li +2
The conventional characterization of topological materials relies on topological invariants calculated from the entire set of occupied bands. However, when a system possesses rotat…
Topological Interstitial-Electron Conductor
Tingli He, Xiaoming Zhang, Chaoxi Cui +5
Electron transport in solids arises primarily from two mechanisms: freely moving bulk electrons in metals, and gapless boundary states in topological insulators. Here, we report a…
Equivariant Space Group and Hamiltonian for Collinear Magnetic Systems
Chaoxi Cui, Zhi-Ming Yu, Yilin Han +3
Condensed matter physics increasingly focuses on exploiting the magnetic order parameter orientation n as a tuning knob for properties of collinear magnetic materials, but a genera…
Electric-Field Control of Terahertz Response via Spin-Corner-Layer Coupling in Altermagnetic Bilayers
Jianhua Wang, Yilin Han, Shifeng Qian +4
Electric field control of electron charge and spin degrees of freedom is fundamental to modern semiconductor and spintronic devices. Yet controlling electromagnetic waves with an e…
Type-II Antiferroelectricity
Yang Wang, Zhi-Ming Yu, Chaoxi Cui +6
Antiferroelectricity (AFE) is a fundamental concept in physics and materials science. Conventional AFEs have the picture of alternating local electric dipoles defined in real space…
Crossed real nodal-line phonons in gold monobromide
Yilin Han, Yichen Liu, Chaoxi Cui +2
Spacetime inversion symmetry can generate intriguing types of spinless excitations in crystalline materials. Here, we propose a topological phase protected by spacetime inversion s…
