In the present work, we investigate the phase transitions of the Ising model with interactions between first (J1), second (J2) and third (J3) neighbours in the square lattice with transverse magnetic field. In this study, ...

Cálculo de la función dieléctrica relativa para un sistema ferroeléctrico con gradaciones que consiste en una estructura alineada (en capas), utilizando el Modelo de Ising Transversal / Abstract: Calculation of the relative ...

In this work we studied the decoherence in a central quantum system S uniformly coupled to a reservoir R, chosen as a quantum Ising chain with transverse field. Initially, we review the usual approach to diagonalize the ...

The spectrum of the fluctuation in the polarization for the Ising Model in a transversal field has been calculated by Mori's continued fraction method in the low temperature region, using the three pole approximation. The ...

A time-periodic magnetic field applied transversally to the hard axis of an extended easy-plane ferromagnetic sample can produce parametric resonance. For the 2:1 resonance, the prototype orderparameter- equation derived ...
