Hubbard model on Semiclassical approximation in combination with an optimizer based on GPU technology
Hayun Park, Hunpyo Lee
We developed a semiclassical approximation method in combination with an adaptive moment estimation optimizer (SCA + ADAM) approach based on the PyTorch plus CUDA library on a the…
Orbital Selective Phase Transition
Yao Yao, Yu-Zhong Zhang, Hunpyo Lee +4
We review theoretical investigations on the origin of the orbital selective phase where localized and itinerant electrons coexist in the d shell at intermediate strength of the on-…
Theoretical prediction of a strongly correlated Dirac metal
I. I. Mazin, Harald O. Jeschke, Frank Lechermann +4
Recently, the most intensely studied objects in the electronic theory of solids have been strongly correlated systems and graphene. However, the fact that the Dirac bands in graphe…
Importance of Itinerancy and Quantum Fluctuations for the Magnetism in Iron Pnictides
Yu-Zhong Zhang, Hunpyo Lee, Ingo Opahle +2
By applying density functional theory, we find strong evidence for an itinerant nature of magnetism in two families of iron pnictides. Furthermore, by employing dynamical mean fiel…
