Spin liquid phase in the Hubbard model: Luttinger-Ward analysis of the slave-rotor formalism
Xia-Ming Zheng, Mehdi Kargarian
We propose an approach for studying the spin liquid phase of the Hubbard model on the triangular lattice by combining the Baym-Kadanoff formalism with the slave rotor parton constr…

Phase diagram of the Kitaev-Hubbard model: slave-spin and QMC approaches
Fatemeh Mohammadi, Mojtaba Tabatabaei, Mehdi Kargarian +1
Recent experiments show that the ground state of some layered materials with localized moments is in close proximity to the Kitaev spin liquid, calling for a proper model to descri…
