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…
Bogoliubov Quasiparticle on the Gossamer Fermi Surface in Electron-Doped Cuprates
Ke-Jun Xu, Qinda Guo, Makoto Hashimoto +14
In contrast to hole-doped cuprates, electron-doped cuprates consistently exhibit strong antiferromagnetic correlations with a commensurate (π, π) ordering wave vector, leading to t…
Emergent normal fluid in the superconducting ground state of overdoped cuprates
Shusen Ye, Miao Xu, Hongtao Yan +7
The microscopic mechanism for the disappearance of superconductivity in overdoped cuprates is still under heated debate. Here we use scanning tunneling spectroscopy to investigate…
Boosting quantum Monte Carlo and alleviating sign problem by Gutzwiller projection
Wei-Xuan Chang, Zi-Xiang Li
Here we develop a new scheme of projective quantum Monte-Carlo (QMC) simulation combining unbiased zero-temperature (projective) determinant QMC and variational Monte-Carlo based o…
Non-Hermitian strongly interacting Dirac fermions: a quantum Monte-Carlo study
Xue-Jia Yu, Zhiming Pan, Limei Xu +1
Exotic quantum phases and phase transition in the strongly interacting Dirac systems has attracted tremendous interests. On the other hand, non-Hermitian physics, usually associate…
Order-by-disorder and emergent Kosterlitz-Thouless phase in triangular Rydberg array
Sibo Guo, Jiangping Hu, Zi-Xiang Li
Programmable quantum simulator using Rydberg-atom array provides a promising route to demystifying quantum many-body physics in strongly correlated systems. Motivated by recent rea…
