Robust spin pseudogap and spin-charge separation in the - model
Zheng-Yuan Yue, Jia-Xin Zhang, Zheng-Cheng Gu
The - model, obtained from the usual - model by flipping the sign of the spin-down hopping term, has been proposed to eliminate the strong interference between doped h…
Momentum-Selective Two-Component Excitations in Electron-Doped Mott Insulators
Zeyu Han, Can Cui, Jia-Xin Zhang +1
Experimental studies reveal a striking asymmetry in low-energy single-particle excitations between electron- and hole-doped cuprates. Electron-doped cuprates display a nontrivial d…
Competing and Intertwined Orders in Boson-Doped Mott Antiferromagnets
Xin Lu, Jia-Xin Zhang, Lukas Homeier +3
Inspired by the recent experimental advances in cold atom quantum simulators, we explore the experimentally implemented bosonic -- model on the square lattice using large…
Revealing quantum phase string effect in doped Mott-insulator: a tensor network state approach
Wayne Zheng, Jia-Xin Zhang, Zheng-Yuan Yue +2
We apply the fermionic tensor network (TN) state method to understand the strongly correlated nature in a doped Mott insulator. We conduct a comparative study of the - model…
Intrinsic phase fluctuation and superfluid density in doped Mott insulators
Zeyu Han, Zhi-Jian Song, Jia-Xin Zhang +1
The doping dependence of the superfluid density exhibits distinct behaviors in the underdoping and overdoping regimes of the cuprate, while the superconducting (SC)…
Quantum-interference-induced pairing in bosonic doped antiferromagnets
Hao-Kai Zhang, Jia-Xin Zhang, Ji-Si Xu +2
The pairing mechanism in doped antiferromagnets is essential for understanding high-temperature superconductivity. In this work, we investigate the pairing mechanism in bosonic dop…
Electric transport in doped Mott insulators dictated by a non-Ioffe-Larkin composition rule and spinons
Chuan Chen, Jia-Xin Zhang, Zhi-Jian Song +1
The electric resistivity is examined in the constrained Hilbert space of a doped Mott insulator, which is dictated by a non-Ioffe-Larkin composition rule due to the underlying mutu…
Vortex structure in a -wave superconductor obtained by a confinement transition from the pseudogap metal
Jia-Xin Zhang, Subir Sachdev
We compute the structure of flux vortices in a d-wave superconductor which emerges from a higher temperature pseudogap metal. Such a transition is described by a continuum…
Strong Pairing Originated from an Emergent Berry Phase in LaNiO
Jia-Xin Zhang, Hao-Kai Zhang, Yi-Zhuang You +1
The recent discovery of high-temperature superconductivity in LaNiO offers a fresh platform for exploring unconventional pairing mechanisms. Starting with the basic arg…
Thermal Hall Effect and Neutral Spinons in a Doped Mott Insulator
Zhi-Jian Song, Jia-Xin Zhang, Zheng-Yu Weng
In the pseudogap phase of the cuprate, a thermal Hall response of neutral objects has been recently detected experimentally, which continuously persists into the antiferromagnetic…
Hourglass-Like Spin Excitation in a Doped Mott Insulator
Jia-Xin Zhang, Chuan Chen, Jian-Hao Zhang +1
We examine the dynamical magnetic response in a two-component resonating-valence-bond (RVB) description of the doped Mott insulator. The half-filled antiferromagnetic phase describ…
