Possible origin of the reduced magnetic moment in iron pnictides: A dynamical mean field theory study
Hunpyo Lee, Yu-Zhong Zhang, Harald O. Jeschke +1
We investigate the phase diagram of a two-band frustrated Hubbard model in the framework of dynamical mean field theory. While a first-order phase transition occurs from a paramagn…

Dynamical cluster approximation study of the anisotropic two-orbital Hubbard model
Hunpyo Lee, Yu-Zhong Zhang, Harald O. Jeschke +2
We investigate the properties of a two-orbital Hubbard model with unequal bandwidths on the square lattice in the framework of the dynamical cluster approximation (DCA) combined wi…

Mott transition in the Hubbard model on the hyper-kagome lattice
Hunpyo Lee, Hartmut Monien
Motivated by recent experiment on the NaIrO compound we study the Hubbard model on the "hyper-kagome lattice", which forms a three-dimensional network of corner sharing…
