Hyperspin Altermagnets
Hai-Yang Ma, Yuanchang Li, Hu Xu +2
The behavior of spin quantum in k-space is key to identifying altermagnets (AMs) as the third kind of fundamental collinear magnetism. In contrast, non-collinear magnets,though abu…
Multicolor groups for molecules and solids
Hai-Yang Ma, Shihao Zhang, Hu Xu +2
The local magnetic moments of atoms in a molecule or solid can be designated by different colors. Magnetic groups, or 2-color groups, or black-and-white groups have been applied in…
Theory for charge density wave and orbital-flux state in antiferromagnetic kagome metal FeGe
Hai-Yang Ma, Jia-Xin Yin, M. Zahid Hasan +1
In this work, we theoretically study the charge order and orbital magnetic properties of a new type of antiferromagnetic kagome metal FeGe. Based on first principles density functi…
Magnetic domain structure and domain wall bound states of topological semimetal EuB6
Qiang Li, Haiyang Ma, Xin Zhang +5
Electrically manipulating domain wall (DW) is at central in the field of spintronics. Magnetic Weyl semimetal (WSM) offers an additional knob for electric manipulation of DW by uti…
Flat bands, non-trivial band topology and electronic nematicity in layered kagome-lattice RbTiBi
Zhicheng Jiang, Zhengtai Liu, Haiyang Ma +15
Layered kagome-lattice materials with 3 transition metals provide a fertile playground for studies on geometry frustration, band topology and other novel ordered states. A repre…
Observation of electronic nematicity driven by three-dimensional charge density wave in kagome lattice KVSb
Zhicheng Jiang, Haiyang Ma, Wei Xia +14
Kagome superconductors AVSb (A = K, Rb, Cs) provide a fertile playground for studying intriguing phenomena, including non-trivial band topology, superconductivity, giant an…
First principles theory for the magnetic and charge instabilities in AVSb systems
Hai-Yang Ma, Jianpeng Liu
Vanadium-based materials AVSb (A=K, Rb, Cs) with layered kagome lattice structures have drawn great attention recently due to the discoveries of topologically nontrivial ba…
Multifunctional Antiferromagnetic Materials with Giant Piezomagnetism and Noncollinear Spin Current
Hai-Yang Ma, Mengli Hu, Nana Li +4
We propose a new type of spin-valley locking (SVL), named -paired SVL, in antiferromagnetic systems, which directly connects the spin/valley space with the real space,…
Braiding Majorana Zero Mode in An Electrically Controllable Way
Hai-Yang Ma, Dandan Guan, Shiyong Wang +4
To realize the braiding operations of Majorana zero mode in the vortex cores of a topological superconductor (TSC), a novel approach is proposed in this letter to replace the commo…
Observation of Majorana fermions with spin selective Andreev reflection in the vortex of topological superconductor
Hao-Hua Sun, Kai-Wen Zhang, Lun-Hui Hu +14
Majorana fermion (MF) whose antiparticle is itself has been predicted in condensed matter systems. Signatures of the MFs have been reported as zero energy modes in various systems.…
