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…

Analysis of the phase transition for the Ising model on the frustrated square lattice
A. Kalz, A. Honecker, M. Moliner
We analyze the phase transition of the frustrated - Ising model with antiferromagnetic nearest- and strong next-nearest neighbor interactions on the square lattice. Using…

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…
