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…
Anomalous Coherence Length in Superconductors with Quantum Metric
Jin-Xin Hu, Shuai A. Chen, K. T. Law
The coherence length is the fundamental length scale of superconductors which governs the sizes of Cooper pairs, vortices, Andreev bound states, and more. In BCS theory, the co…
Weak Ergodicity Breaking in Non-Hermitian Many-body Systems
Qianqian Chen, Shuai A. Chen, Zheng Zhu
The recent discovery of persistent revivals in the Rydberg-atom quantum simulator has revealed a weakly ergodicity-breaking mechanism dubbed quantum many-body scars, which are a se…
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…
