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…

Spinon Kondo lattice in quantum spin liquids
Xia-Ming Zheng, Mehdi Kargarian
Motivated by recent experimental observations of Kondo resonances in cobalt atoms on single layer 1T-TaSe, we theoretically investigate the effect of coupling a U(1) quantum…
