Charge order and superconductivity in a minimal two-band model for infinite-layer nickelates
Cheng Peng, Hong-Chen Jiang, Brian Moritz +2
The recent discovery of superconductivity in infinite-layer nickelates has drawn considerable attention; however, a consensus on the fundamental building blocks and common ingredie…
Doping quantum spin liquids on the Kagome lattice
Cheng Peng, Yi-Fan Jiang, Dong-Ning Sheng +1
We review recent density-matrix renormalization group (DMRG) studies of lightly doped quantum spin liquids (QSLs) on the kagome lattice. While a number of distinct conducting phase…
Gapless spin liquid and pair density wave of the Hubbard model on three-leg triangular cylinders
Cheng Peng, Yi-Fan Jiang, Yao Wang +1
We study the ground state properties of the Hubbard model on three-leg triangular cylinders using large-scale density-matrix renormalization group simulations. At half-filling, we…
Evidence of pair-density wave in doping Kitaev spin liquid on the honeycomb lattice
Cheng Peng, Yi-Fan Jiang, Thomas P. Devereaux +1
We study the effects of doping the Kitaev model on the honeycomb lattice where the spins interact via the bond-directional interaction , which is known to have a quantum spin…
Efficient Quantum Simulation for Thermodynamics of Infinite-size Many-body Systems in Arbitrary Dimensions
Shi-Ju Ran, Bin Xi, Cheng Peng +2
In this work we propose to simulate many-body thermodynamics of infinite-size quantum lattice models in one, two, and three dimensions, in terms of few-body models of only O(10) si…
Thermodynamics of Spin-1/2 Kagomé Heisenberg Antiferromagnet: Algebraic Paramagnetic Liquid and Finite-Temperature Phase Diagram
Xi Chen, Shi-Ju Ran, Tao Liu +3
Quantum fluctuations from frustration can trigger quantum spin liquids (QSLs) at zero temperature. However, it is unclear how thermal fluctuations affect a QSL. We employ state-of-…
