Pair-Density Wave from Doping an Altermagnetic Mott Insulator

Shuai A. Chen, Qianqian Chen, Guangyu Yu +1

Pair-density-wave (PDW) superconductivity is a state in which the superconducting order parameter modulates at a finite wavevector. Using large-scale density matrix renormalization…

Thermal states emerging from low-entanglement background in disordered spin models

Yule Ma, Qianqian Chen, Mingyang Li +2

Thermalization in isolated quantum systems is governed by the eigenstate thermalization hypothesis, while strong disorder can induce its breakdown via many-body localization. Here…

Geometric Frustration Assisted Kinetic Ferromagnetism in Doped Mott Insulators

Qianqian Chen, Shuai A. Chen, Zheng Zhu

Understanding ferromagnetism mechanism in doped Mott insulators on frustrated lattices remains challenging at intermediate coupling and finite doping. Here, we study the itinerant…

Mean Field Study of Superconductivity in the Square Lattice - Model with Three-Site Hopping

Ke Yang, Qianqian Chen, Lei Qiao +1

It remains an open question whether the two-dimensional single-band pure Hubbard model and its related pure - model truly capture the superconducting order in cuprates. Recen…

Phase Diagram of the Square-Lattice -- Model for Electron-Doped Cuprates

Qianqian Chen, Lei Qiao, Fuchun Zhang +1

Motivated by significant discrepancies between experimental observations of electron-doped cuprates and numerical results of the Hubbard and - models, we investigate the role…
