These phases can occur in frustrated quantum magnets, such as the paradigmatic Heisenberg model with nearest-and next-nearest-neighbor exchange interactions on the triangular lattice, the so-called J1 -J2 model. In this work, we compute the spectral function using large-scale matrix product state ...
We estimate, using a large-scale Monte Carlo simulation, the critical exponents of the antiferromagnetic Heisenberg model on a stacked triangular lattice. We obtain the following estimates: γ/ν= 2.011 ±0.014, ν= 0.585 ±0.009. These results contradict a perturbative 2 + ϵ Renormalization ...

We investigate the effect of ring-exchange on the ground-state properties andmagnetic excitations of the $S = 1/2$ Heisenberg model on the anisotropictriangular lattice with ring-exchange at $T = 0$ using linear spin-wave theory.Classically, we find stable N\\'{e}el, spiral and collinear...

The Kitaev-Heisenberg (KH) model has been proposed to capture magneticinteractions in iridate Mott insulators on the honeycomb lattice. We show thatanalogous interactions arise in many other geometries built from edge-sharingIrO_6 octahedra, including the pyrochlore and hyperkagome lattices relevant toIr...

Finite-temperature phase transition to a quantum spin liquid in a 3D Kitaev model The Kitaev model has recently attracted considerable attention due to the spin-liquid ground states. This model is defined on a honeycomb lattice, and is exactly solvable due to the Ising conserved quantities associat...
At the same time, the ring exchange coupling is found to drive the system into a state with more short ranged spin correlation and with a local spin correlation pattern equivalent to that of the antiferromagnetic Heisenberg model on triangular lattice(the peak of spin structure factor moves to ...
