Results are presented for a Floquet Ising chain with duality twisted boundary conditions, taking into account the role of weak integrability breaking in the form of four-fermion interactions. In the integrable case, a single isolated Majorana zero mode exists which is a symmetry in …

We then apply those steps to the Ising model and thereby solve it in the l...
WitrynaConsider the Ising model, in zero magnetic field, on a N ∗ x × N ∗ y square lattice, with N ∗ x, y → ∞ in the thermodynamic limit. Along the perimeter of the system we impose … WitrynaResults on Ising models are reviewed in connection with experimental findings on ferroelectric and ferromagnetic materials. In particular, models with competing interactions, like the ANNNI model and an Ising system with dipolar interactions, are discussed, and applications of Monte Carlo coarse graining are presented.
