Vertex-based Diagrammatic Treatment of Light-Matter-Coupled Systems
Aaram J. Kim, Katharina Lenk, Jiajun Li +2
We propose a diagrammatic Monte Carlo approach for general spin-boson models, which can be regarded as a generalization of the strong-coupling expansion for fermionic impurity mode…

J-freezing and Hund's rules in spin-orbit-coupled multiorbital Hubbard models
Aaram J. Kim, Harald O. Jeschke, Philipp Werner +1
We investigate the phase diagram of the spin-orbit-coupled three orbital Hubbard model at arbitrary filling by means of dynamical mean-field theory combined with continuous-time qu…

Finite-temperature phase transitions in the ionic Hubbard model
Aaram J. Kim, M. Y. Choi, Gun Sang Jeon
We investigate paramagnetic metal-insulator transitions in the infinite-dimensional ionic Hubbard model at finite temperatures. By means of the dynamical mean-field theory with an…
