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…
Local spectroscopy of loop current order with individual magnetic atoms
Jiangchang Zheng, Caiyun Chen, Xu Zhang +16
Hidden ordered states--characterized by order parameters that elude conventional probes--pose a fundamental challenge for their identification in quantum materials. Recent experime…
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…
