Engineering excitonic metal-insulator transitions in ultra-thin doped copper sulfides
Haiyang Chen, Yufeng Liu, Yashi Jiang +10
Delicate engineering of the bands remains challenging due to complex electronic, structural, and compositional interplay. We demonstrate the formation of distinct metallic and insu…

Atomic-Scale Imaging of Fractional Spinon Quasiparticles in Open-Shell Triangulene Spin- Chains
Zhangyu Yuan, Xin-Yu Zhang, Yashi Jiang +14
The emergence of spinon quasiparticles, which carry spin but lack charge, is a hallmark of collective quantum phenomena in low-dimensional quantum spin systems. While the existence…

Artificially built Kondo chains with organic radicals on metallic surfaces: new model system of heavy fermion quantum criticality
En Li, Bimla Danu, Yufeng Liu +6
Heavy fermion quantum criticality is an extremely rich domain of research which represents a framework to understand strange metals as a consequence of a Kondo breakdown transition…
