Superconductivity in lightly doped Hubbard model on honeycomb lattice
Cheng Peng, D. N. Sheng, Hong-Chen Jiang
We have performed large-scale density-matrix renormalization group studies of the lightly doped Hubbard model on the honeycomb lattice on long three and four-leg cylinders. We find…
Traces of Electron-Phonon Coupling in One-Dimensional Cuprates
Ta Tang, Brian Moritz, Cheng Peng +2
The appearance of certain spectral features in one-dimensional (1D) cuprate materials has been attributed to a strong, extended attractive coupling between electrons. Here, using t…
Enhanced superconductivity by near-neighbor attraction in the doped Hubbard model
Cheng Peng, Yao Wang, Jiajia Wen +3
Recent experiment has unveiled an anomalously strong electron-electron attraction in one-dimensional copper-oxide chain BaSrCuO. While the near-neighbor electro…
Disordered vector models: from higher spins to incipient strings
Chi-Ming Chang, Sean Colin-Ellerin, Cheng Peng +1
We present a one-parameter family of large disordered models, with and without supersymmetry, in three spacetime dimensions. They interpolate from the critical large vector…
