Emergent quantum phenomena in two-dimensional 1T-TaS2
Haiyang Chen, Zhiqiang Sun, Peng Chen
Strong electron correlation drives 1T-TaS2 from a half-filled metallic state into a Mott insulating phase, coexisting with a charge density wave at low temperatures. Under external…
Orbital textures and evolution of correlated insulating state in monolayer 1T phase transition metal dichalcogenides
Qiang Gao, Haiyang Chen, Wen-shin Lu +5
Strong electron-electron interaction can induce Mott insulating state, which is believed to host unusual correlated phenomena such as quantum spin liquid when quantum fluctuation d…
Spectroscopic evidence for possible quantum spin liquid behavior in a two-dimensional Mott insulator
Haiyang Chen, Fo-Hong Wang, Qiang Gao +6
Mott insulators with localized magnetic moments will exhibit a quantum spin liquid (QSL) state when the quantum fluctuations are strong enough to suppress the ordering of the spins…
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…
