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…
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…
