Chiral fermion reversal in chiral crystals
Hang Li, Sheng Xu, Zhi-Cheng Rao +13
In materials chiral fermions such as Weyl fermions are characterized by nonzero chiral charges, which are singular points of Berry curvature in momentum space. Recently, new types…
Magneto-memristive switching in a two-dimensional layer antiferromagnet
Hyun Ho Kim, Shengwei Jiang, Bowen Yang +7
Memristive devices whose resistance can be hysteretically switched by electric field or current are intensely pursued both for fundamental interest as well as potential application…

Intrinsic anomalous Nernst effect amplified by disorder in a half-metallic semimetal
Linchao Ding, Jahyun Koo, Liangcai Xu +9
Intrinsic anomalous Nernst effect (ANE), like its Hall counterpart, is generated by Berry curvature of electrons in solids. Little is known about its response to disorder. In contr…
Magnetic-field control of topological electronic response near room temperature in correlated Kagome magnets
Yangmu Li, Qi Wang, Lisa DeBeer-Schmitt +13
Strongly correlated Kagome magnets are promising candidates for achieving controllable topological devices owing to the rich interplay between inherent Dirac fermions and correlati…

Evolution of interlayer and intralayer magnetism in three atomically thin chromium trihalides
Hyun Ho Kim, Bowen Yang, Siwen Li +16
We conduct a comprehensive study of three different magnetic semiconductors, CrI, CrBr, and CrCl, by incorporating both few- and bi-layer samples in van der Waals tunne…
New classes of chiral topological nodes with non-contractible surface Fermi arcs in CoSi
Z. -C. Rao, H. Li, T. -T. Zhang +18
In condensed matter systems, chiral topological nodes are robust band crossing points in momentum space that carry nonzero Chern numbers. The chirality is manifested by the presenc…
Local orbital degeneracy lifting as a precursor to an orbital-selective Peierls transition
E. S. Bozin, W. G. Yin, R. J. Koch +7
Fundamental electronic principles underlying all transition metal compounds are the symmetry and filling of the -electron orbitals and the influence of this filling on structura…
