Spectroscopic fingerprints of a ferroaxial charge density wave
Jiangchang Zheng, Zhongyi Zhang, Fazhi Yang +11
Unconventional charge density waves (CDWs) with complex order parameters can host exotic collective modes and non-trivial topologies. They have emerged as a new frontier in the stu…
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…
Discovery of an odd-parity f-wave charge order in a kagome metal
Jiangchang Zheng, Caiyun Chen, Ruiqin Fu +13
The spontaneous breaking of symmetries is a cornerstone of physics, defining the phases of matter from the cosmological scale to the quantum realm. In condensed matter, electronic…
Interplay of ferromagnetism, nematicity and Fermi surface nesting in kagome flat band
Yuman He, Wentao Jiang, Siqi Wu +4
Recent experiment on Fe-doped CoSn has uncovered a series of correlated phases upon hole doping of the kagome flat bands. Among the phases observed, a nematic phase with a six- to…
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…
Quasiparticle Spectroscopy of Chiral Charge Order
Jiangchang Zheng, Caiyun Chen, Gaopei Pan +11
Electronic interactions can give rise to novel charge density waves with unconventional ground states. Recent experiments report evidence for a chiral charge density wave (CDW) tha…
