Quantum metric nonlinear Hall effect in a topological antiferromagnetic heterostructure
Anyuan Gao, Yu-Fei Liu, Jian-Xiang Qiu +28
Quantum geometry - the geometry of electron Bloch wavefunctions - is central to modern condensed matter physics. Due to the quantum nature, quantum geometry has two parts, the real…
Axion optical induction of antiferromagnetic order
Jian-Xiang Qiu, Christian Tzschaschel, Junyeong Ahn +25
Using circularly-polarized light to control quantum matter is a highly intriguing topic in physics, chemistry and biology. Previous studies have demonstrated helicity-dependent opt…
Topological Circular Dichroism in Chiral Multifold Semimetals
Junyeong Ahn, Barun Ghosh
Uncovering the physical contents of the nontrivial topology of quantum states is a critical problem in condensed matter physics. Here, we study the topological circular dichroism i…
Discovery of a magnetic Dirac system with large intrinsic non-linear Hall effect
Federico Mazzola, Barun Ghosh, Jun Fujii +9
Magnetic materials exhibiting topological Dirac fermions are attracting significant attention for their promising technological potential in spintronics. In these systems, the comb…
