چکیده
By means of extensive computer simulations we analyze in detail the two dimensional ±J Ising spin glass with ferromagnetic next-nearest-neighbor interactions. We found a crossover from ferromagnetic to “spin glass” like order both from numerical simulations and analytical arguments. We also present evidences of a second crossover from the “spin glass” behavior to a paramagnetic phase for the largest volume studied.

Crossovers in the two-dimensional Ising spin glass with ferromagnetic next-nearest-neighbour interactions
By means of extensive computer simulations we analyse in detail the twodimensional ±J Ising spin glass with ferromagnetic next-nearest-neighbour interactions. We found a crossover from ferromagnetic to ‘spin glass’-like order both from numerical simulations and analytical arguments. We also present proof of a second crossover from the ‘spin glass’ behaviour to a paramagnetic phase for the large...
متن کاملHigh order perturbation study of the frustrated quantum Ising chain
In this paper, using high order perturbative series expansion method, the critical exponents of the order parameter and susceptibility in transition from ferromagnetic to disordered phases for 1D quantum Ising model in transverse field, with ferromagnetic nearest neighbor and anti-ferromagnetic next to nearest neighbor interactions, are calculated. It is found that for small value of the frustr...
متن کاملNumerically exact correlations and sampling in the two-dimensional Ising spin glass.
A powerful existing technique for evaluating statistical mechanical quantities in two-dimensional Ising models is based on constructing a matrix representing the nearest-neighbor spin couplings and then evaluating the Pfaffian of the matrix. Utilizing this technique and other more recent developments in evaluating elements of inverse matrices and exact sampling, a method and computer code for s...
متن کاملPhase transitions in the two-dimensional superantiferromagnetic Ising model with next-nearest-neighbor interactions.
We use Monte Carlo and transfer matrix methods in combination with extrapolation schemes to determine the phase diagram of the two-dimensional superantiferromagnetic (SAF) Ising model with next-nearest-neighbor (NNN) interactions in a magnetic field. The interactions between nearest-neighbor (NN) spins are ferromagnetic along x, and antiferromagnetic along Y. We find that for sufficiently low t...
متن کاملThe Two Dimensional Antiferromagnetic Heisenberg Model with next Nearest Neighbour Ising Exchange
We have studied the S = 1/2 antiferromagnetic Heisenberg model in two dimensions, with an additional Ising next-nearest neighbour interaction. The next-nearest neighbour Ising interaction breaks the isotropy in spin space, for a ferromagnetic next-nearest neighbour interaction the system will order antiferromagnetically along the z axis. Antiferromagnetic next-nearest neighbour interactions wil...
