High-temperature superconductivity induced by the Su-Schrieffer-Heeger electron-phonon coupling
Xun Cai, Zi-Xiang Li, Hong Yao
Experimental quest for high-temperature and room-temperature superconductivity (SC) at ambient pressure has been a long-standing research theme in physics. It has also been desired…
Spectral properties of 1D extended Hubbard model from bosonization and time-dependent variational principle: applications to 1D cuprate
Hao-Xin Wang, Yi-Ming Wu, Yi-Fan Jiang +1
Recent ARPES experiments on doped 1D cuprates revealed the importance of effective near-neighbor (NN) attractions in explaining certain features in spectral functions. Here we inve…
Robust d-wave superconductivity from the Su-Schrieffer-Heeger-Hubbard model: possible route to high-temperature superconductivity
Hao-Xin Wang, Yi-Fan Jiang, Hong Yao
Increasing numerical studies showed that the simplest Hubbard model on the square lattice with strong repulsion may not exhibit high-temperature superconductivity (SC). It is desir…
Asymptotic sign free in interacting fermion models
Zi-Xiang Li, Zhou-Quan Wan, Hong Yao
As an intrinsically-unbiased approach, quantum Monte Carlo (QMC) is of vital importance in understanding correlated phases of matter. Unfortunately, it often suffers notorious sign…
Robustness of Antiferromagnetism in the Su-Schrieffer-Heeger-Hubbard model
Xun Cai, Zi-Xiang Li, Hong Yao
We recently unveiled that antiferromagnetism (AFM) order can be dominantly induced by the bond Su-Schrieffer-Heeger (SSH) electron-phonon coupling (EPC), which is beyond the conven…
Magic-angle Twisted Bilayer Systems with Quadratic-Band-Touching: Exactly Flat Bands with High-Chern Number
Ming-Rui Li, Ai-Lei He, Hong Yao
Studies of twisted moiré systems have been mainly focused on two-dimensional (2D) materials such as graphene with Dirac points and transition-metal-dichalcogenide so far. Here we p…
