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…

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…

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…
