Topological floating phase in a spatially anisotropic frustrated Ising model
A. Kalz, G. Chitov
We present new results for the ordering process of a two-dimensional Ising model with anisotropic frustrating next-nearest-neighbor interactions. We concentrate on a specific wide…
Location of the Potts-critical end point in the frustrated Ising model on the square lattice
A. Kalz, A. Honecker
We report on Monte Carlo simulations for the two-dimensional frustrated - Ising model on the square lattice. Recent analysis has shown that for the phase transition from…
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…
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…
Monte Carlo studies of the Ising square lattice with competing interactions
A. Kalz, A. Honecker, S. Fuchs +1
We use improved Monte-Carlo algorithms to study the antiferromagnetic 2D-Ising model with competing interactions on nearest neighbour and on next-nearest neighbour bond…
Phase diagram of the Ising square lattice with competing interactions
A. Kalz, A. Honecker, S. Fuchs +1
We restudy the phase diagram of the 2D-Ising model with competing interactions on nearest neighbour and on next-nearest neighbour bonds via Monte-Carlo simulations. We…
