Plaquette ordered phase and quantum spin liquid in the spin-12 J1-J2 square Heisenberg model
superconductivity of strongly correlated systems[2]. The exciting properties of spin liquids such as deconfined quasiparticles and fractional statistics have been revealed in many artificially constructed systems such as quantum dimer models[3– 5], Kagome spin model in the easy axis limit[6–10], and Kitaev model[11]. The possibility of finding spin liquids in realistic Heisenberg models, which ...

In this study, the effect of four-spin exchanges between the nearest and next nearest neighbor spins of honeycomb lattice on the phase diagram of S=3/2 antiferomagnetic Heisenberg model is considered with two-spin exchanges between the nearest and next nearest neighbor spins. Firstly, the method is investigated with classical phase diagram. In classical phase diagram, in addition to Neel order,...

متن کاملPhase diagram and Fermi liquid properties of the extended Hubbard model on the honeycomb lattice
The Hubbard and extended Hubbard models on the honeycomb lattice can be seen as prototype models of a single-layer graphene placed in a high dielectric constant environment that screens the Coulomb interaction. Taking advantage of the absence of a sign problem at half-filling, we study this problem with clusters up to 96 sites with the determinant quantum Monte Carlo method as an impurity solve...
