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…
Nonlinear optical diode effect in a magnetic Weyl semimetal
Christian Tzschaschel, Jian-Xiang Qiu, Xue-Jian Gao +18
Diode effects are of great interest for both fundamental physics and modern technologies. Electrical diode effects (nonreciprocal transport) have been observed in Weyl systems. Opt…
Electronic ratchet effect in a moiré system: signatures of excitonic ferroelectricity
Zhiren Zheng, Xueqiao Wang, Ziyan Zhu +17
Electronic ferroelectricity represents a new paradigm where spontaneous symmetry breaking driven by electronic correlations, in contrast to traditional lattice-driven ferroelectric…
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…
Photocurrent as a multi-physics diagnostic of quantum materials
Qiong Ma, Roshan Krishna Kumar, Su-Yang Xu +2
The photoexcitation life-cycle from incident photon (and creation of photoexcited electron hole pair) to ultimate extraction of electrical current is a complex multi-physics proces…
Theory of optical axion electrodynamics and application to the Kerr effect in topological antiferromagnets
Junyeong Ahn, Su-Yang Xu, Ashvin Vishwanath
Emergent axion electrodynamics in magneto-electric media is expected to provide novel ways to detect and control material properties with electromagnetic fields. However, despite b…
