Distinguishing and Separating In-Plane Hall Responses
Soumya Sankar, Xingkai Cheng, Junwei Liu +1
Electric Hall effects generated by an in-plane magnetic field have recently gained attention owing to their intrinsic origin in topological electronic states and potential applicat…
Broadband nonlinear Hall response and multiple wave mixing in a room temperature altermagnet
Soumya Sankar, Xingkai Cheng, Xinyu Chen +10
Crystalline symmetries determine the linear and nonlinear response of materials to external stimuli such as mechanical pressure and electromagnetic fields, governing phenomena such…
Room temperature observation of the anomalous in-plane Hall effect in epitaxial thin films of a Weyl ferromagnet
Soumya Sankar, Xingkai Cheng, Tahir Murtaza +7
Topologically nontrivial electronic states can give rise to novel anomalous Hall effects. The potential appearance of these effects at room temperature holds promise for their appl…
Cascade of strongly correlated quantum states in a partially filled kagome flat band
Caiyun Chen, Jiangchang Zheng, Yuman He +7
Coulomb interactions among charge carriers that occupy an electronic flat band have a profound impact on the macroscopic properties of materials. At sufficient strength, these inte…
Visualizing the Localized Electrons of a Kagome Flat Band
Caiyun Chen, Jiangchang Zheng, Ruopeng Yu +4
Destructive interference between electron wavefunctions on the two-dimensional (2D) kagome lattice induces an electronic flat band, which could host a variety of interesting many-b…
Experimental evidence for Berry curvature multipoles in antiferromagnets
Soumya Sankar, Ruizi Liu, Xue-Jian Gao +12
Berry curvature multipoles appearing in topological quantum materials have recently attracted much attention. Their presence can manifest in novel phenomena, such as nonlinear anom…
