Unsupervised machine learning account of magnetic transitions in the Hubbard model
Kelvin Ch'ng, Nick Vazquez, Ehsan Khatami
We employ several unsupervised machine learning techniques, including autoencoders, random trees embedding, and t-distributed stochastic neighboring ensemble (t-SNE), to reduce the…
Exotic pairing symmetry of interacting Dirac fermions on a flux lattice
Huaiming Guo, Ehsan Khatami, Yao Wang +3
The pairing symmetry of interacting Dirac fermions on the -flux lattice is studied with the determinant quantum Monte Carlo and numerical linked cluster expansion methods. The e…
Competing phases and orbital-selective behaviors in the two-orbital Hubbard-Holstein model
Shaozhi Li, Ehsan Khatami, Steven Johnston
We study the interplay between the electron-electron (e-e) and the electron-phonon (e-ph) interactions in the two-orbital Hubbard-Holstein model at half filling using the dynamical…
