Role of interstitial orbital in a model of infinite-layer nickelates
Yan Peng, Rui Peng, Mi Jiang
Motivated by recent angle-resolved photoemission spectroscopy (ARPES) experiments on infinite-layer (IL) nickelates, we employ determinant quantum Monte Carlo (DQMC) to study the t…
Checkerboard-type Zhang-Rice States in Overdoped Cuprate Superconductors
Xiongfang Liu, Kun Han, Yan Peng +13
Cuprate superconductors remain central to condensed matter physics due to their technological relevance and unconventional, incompletely understood electronic behavior. While the c…
Interplay between Hubbard interaction and charge transfer energy in three-orbital Emery model: implication on cuprates and nickelates
Yan Peng, Mi Jiang
We use the numerically unbiased determinant quantum Monte Carlo (DQMC) method to systematically investigate the three-orbital Emery model in the normal state in a wide range of loc…
Hole clustering and mutual interplay in three-band Hubbard model
Mi Jiang, Yi-feng Yang, Guang-Ming Zhang
Recent scanning tunnelling spectroscopy (STS) experiments revealed remarkable role of a supercell consisting CuO unit cells in the emergence of local nematic state a…
Anisotropic multi-orbital Hubbard model simulated with impurity approximation
Yan Peng, Mi Jiang
Motivated by the recent experimental findings on the orbital ordering of cuprate SC, we have investigated the multi-orbital Hubbard model in the framework of Cu impurity approximat…
