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…
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…
Directionally Locked Heteroepitaxy with a Structurally Modulated van der Waals Material
Nitish Mathur, Guangming Cheng, Francesc Ballester +17
Precise orientation of symmetry-mismatched epilayers on van der Waals (vdW) substrates via heteroepitaxy has commonly been achieved through surface treatment processes to accommoda…
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…
