Robust fluctuating intertwined charge stripes in the Emery model
Rong Zhang, Sijia Zhao, Hong-Chen Jiang +3
The single-band Hubbard model is one of the most extensively studied models in condensed matter physics, giving rise to intertwined spin and charge stripes that coexist with, or li…

Solitons with irrational charge in a one-dimensional quantum ferroelectric
Sijia Zhao, Steven A. Kivelson
We use analytic (mean-field) and density-matrix renormalization group (DMRG) methods to study a simplified one-dimensional version of the SSH-Holstein model of electron-phonon inte…
