Quantum fidelity approach to the ground state properties of the 1D ANNNI model in a transverse field
O. F. de Alcantara Bonfim, B. Boechat, J. Florencio
In this work we analyze the ground-state properties of the one-dimensional ANNNI model in a transverse field using the quantum fidelity approach. We numerically determined…
Critical behavior of a quantum chain with four-spin interactions in the presence of longitudinal and transverse magnetic fields
B. Boechat, J. Florencio, A. Saguia +1
We study the ground-state properties of a spin-1/2 model on a chain containing four-spin Ising-like interactions in the presence of both transverse and longitudinal magnetic fields…
Phase transitions in the two-dimensional super-antiferromagnetic Ising model with next-nearest-neighbor interactions
A. saguia, B. Boechat, O. F. de Alcantara Bonfim +1
We use Monte Carlo and Transfer Matrix methods in combination with extrapolation schemes to determine the phase diagram of the 2D super-antiferromagnetic (SAF) Ising model with nex…
