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…
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…
Quantum 2-Body Hamiltonian for Topological Color Codes
H. Bombin, M. Kargarian, M. A. Martin-Delgado
We introduce a two-body quantum Hamiltonian model with spins-$\half$ located on the vertices of a 2D spatial lattice. The model exhibits an exact topological degeneracy in all coup…
Topological Color Codes and Two-Body Quantum Lattice Hamiltonians
M. Kargarian, H. Bombin, M. A. Martin-Delgado
Topological color codes are among the stabilizer codes with remarkable properties from quantum information perspective. In this paper we construct a four-valent lattice, the so cal…
Phase Diagram and Entanglement of Ising Model With Dzyaloshinskii-Moriya Interaction
R. Jafari, M. Kargarian, A. Langari +1
We have studied the phase diagram and entanglement of the one dimensional Ising model with Dzyaloshinskii-Moriya (DM) interaction. We have applied the quantum renormalization group…
