Strong Room-Temperature Bulk Nonlinear Hall Effect in a Spin-Valley Locked Dirac Material
Lujin Min, Hengxin Tan, Zhijian Xie +8
Nonlinear Hall effect (NLHE) is a new type of Hall effect with wide application prospects. Practical device applications require strong NLHE at room temperature (RT). However, prev…
Search for light dark matter with ionization signals in the PandaX-4T Experiment
PandaX Collaboration
We report the search results of light dark matter through its interactions with shell electrons and nuclei, using the commissioning data from the PandaX-4T liquid xenon detector. L…
Pressured-induced superconductivity extending across the topological phase transition in thallium-based topological materials TlBi(S1-xSex)2
Cuiying Pei, Peihao Huang, Peng Zhu +15
The coexistence of superconductivity and topology holds the potential to realize exotic quantum states of matter. Here we report that superconductivity induced by high pressure in…
Electrical switching of ferro-rotational order in nano-thick 1T-TaS crystals
Gan Liu, Tianyu Qiu, Kuanyu He +13
Hysteretic switching of domain states is a salient character of all ferroic materials and the foundation for their multifunctional applications. Ferro-rotational order is emerging…
Unification of Nonlinear Anomalous Hall Effect and Nonreciprocal Magnetoresistance in Metals by the Quantum Geometry
Daniel Kaplan, Tobias Holder, Binghai Yan
The quantum geometry has significant consequences in determining transport and optical properties in quantum materials. Here, we use a semiclassical formalism coupled with perturba…
Electronic nematicity without charge density waves in titanium-based kagome metal
Hong Li, Siyu Cheng, Brenden R. Ortiz +8
Layered crystalline materials that consist of transition metal atoms on a kagome network have emerged as a versatile platform to study unusual electronic phenomena. For example, in…
