Time-reversal-odd Transport in Odd-Parity Magnets
Ling Bai, Si Li, Libor Šmejkal +2
Unconventional magnets combining vanishing net magnetization with spin-split electronic structures and anomalous transport have attracted considerable attention. Using spin-group s…
Two-Dimensional Altermagnetic Iron Oxyhalides: Real Chern Topology and Valley-Spin-Lattice Coupling
Yong-Kun Wang, Si Li, Shengyuan A. Yang
Altermagnets, a novel class of collinear magnetic materials, exhibit unique spin-split band structures, yet topological insulating states in intrinsic altermagnetic systems are rar…
Upper bound of a band complex
Si Li, Zeying Zhang, Xukun Feng +5
Band structure for a crystal generally consists of connected components in energy-momentum space, known as band complexes. Here, we explore a fundamental aspect regarding the maxim…
Berry curvature dipole and nonlinear Hall effect in two-dimensional NbSiTe
Yiwei Zhao, Jin Cao, Zeying Zhang +4
Recent experiments have demonstrated interesting physics in a family of two-dimensional (2D) composition-tunable materials NbSiTe. Here, we show that owing to…
Two-dimensional hourglass Weyl nodal loop in monolayer Pb(ClO) and Sr(ClO)
Xin-Yue Kang, Chunmei Zhang, Mingxing Chen +1
The hourglass fermions in solid-state materials have been attracting significant interest recently. However, realistic two-dimensional (2D) materials with hourglass-shaped band str…
Switchable Topological Phase Transition and Novel Nonlinear Optical Properties in ReC2H Monolayer
Chunmei Zhang, Hanqi Pi, Liqin Zhou +4
Extensive investigations on topological phase transition (TPT) in three-dimensional compounds have been done. whereas, rare in two-dimensional systems, let alone noncentrosymmetric…
