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…
Spin Texture in Doped Mott Insulators with Spin-Orbit Coupling
Shuai A. Chen, Zheng-Yu Weng, Jan Zaanen
A hole injected into a Mott insulator will gain an internal structure as recently identified by exact numerics, which is characterized by a nontrivial quantum number whose nature i…
Two-Hole Ground State: Dichotomy in Pairing Symmetry
Jing-Yu Zhao, Shuai A. Chen, Hao-Kai Zhang +1
A single-hole ground state Ansatz for the two-dimensional t-J model has been recently studied by the variational Monte Carlo (VMC) method. Such a doped hole behaves like a "twisted…
Critical role of the sign structure in the doped Mott insulator: Superconductivity vs. Fermi liquid
Hong-Chen Jiang, Shuai Chen, Zheng-Yu Weng
Mechanism of superconductivity (SC) in a purely interacting electron system has been one of the most challenging issues in condensed matter physics. In the BCS theory, the Landau's…
Single-hole wave function in two dimensions: A case study of the doped Mott insulator
Shuai Chen, Qing-Rui Wang, Yang Qi +2
We study a ground-state ansatz for the single-hole doped - model in two dimensions via a variational Monte Carlo (VMC) method. Such a single-hole wave function possesses fini…
Two-hole ground state wavefunction: Non-BCS pairing in a - two-leg ladder system
Shuai Chen, Zheng Zhu, Zheng-Yu Weng
Superconductivity is usually described in the framework of the Bardeen-Cooper-Schrieffer (BCS) wavefunction, which even includes the resonating-valence-bond (RVB) wavefunction prop…
