Anisotropic frustrated Heisenberg model on the honeycomb lattice
A. Kalz, M. Arlego, D. Cabra +2
We investigate the ground-state phase diagram of an anisotropic Heisenberg model on the honeycomb lattice with competing interactions. We use quantum Monte Carlo simulations, as we…

Quantum disordered ground state for the frustrated square lattice
A. Kalz, A. Honecker, S. Fuchs +1
We present Quantum Monte-Carlo simulations of an exchange-anisotropic spin-1/2 Heisenberg model on a square lattice with nearest and next-nearest neighbor interactions. The ground…

Quantum disordered ground state for hard-core bosons on the frustrated square lattice
A. Kalz, A. Honecker, S. Fuchs +1
We investigate the phase diagram of hard-core bosons on a square lattice with competing interactions. The hard-core bosons can be represented also by spin-1/2 operators and the mod…
