Baby universes, ensemble averages and factorizations with matters
Cheng Peng, Jia Tian, Jianghui Yu
We investigate 2D topological gravity theories with matter fields turned on. We compute correlators of boundary creation operators with extra matter insertions. We provide a system…
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…
A 3d disordered superconformal fixed point
Chi-Ming Chang, Sean Colin-Ellerin, Cheng Peng +1
We initiate the study of a three dimensional disordered supersymmetric field theory. Specifically, we consider a large Wess-Zumino like model with cubic superpo…
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…
Nature of polaron-molecule transition in Fermi polarons
Cheng Peng, Ruijin Liu, Wei Zhang +1
In this work, we explore the polaron and molecule physics by utilizing a unified variational ansatz with up to two particle-hole(p-h) excitations(V-2ph). We confirm the existence o…
