Ising field
Witryna3 sie 2024 · A bstract. We study Ising Field Theory (the scaling limit of Ising model near the Curie critical point) in pure imaginary external magnetic field. We put particular emphasis on the detailed structure of the Yang-Lee edge singularity. While the leading singular behavior is controlled by the Yang-Lee fixed point (= minimal CFT \mathcal … The transverse field Ising model is a quantum version of the classical Ising model. It features a lattice with nearest neighbour interactions determined by the alignment or anti-alignment of spin projections along the axis, as well as an external magnetic field perpendicular to the axis (without loss of generality, along the axis) which creates an energetic bias for one x-axis spin direction over the other.

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 the boundary condition σ ∗ i = + 1. Any configuration of the spins may then be represented uniquely in the following manner. Witryna12 kwi 2024 · We study the residual entropy of a two-dimensional Ising model with crossing and four-spin interactions, both in the case of a zero magnetic field and in an imaginary magnetic field i π / 2 k B T.The spin configurations of this Ising model can be mapped into the hydrogen configurations of square ice with the defined standard …
