We present analytic evidence for the occurrence of an upsilon point, an infinite checkerboard structure of modulated phases, in the ground state of a spin model with uniaxial modulation. The structure of the upsilon point is studied by calculating interface-interface interactions using an expansion in inverse spin anisotropy.

Abstract
We present analytic evidence for the occurrence of an upsilon point, an infinite checkerboard structure of modulated phases, in the ground state of a spin model with uniaxial modulation. The structure of the upsilon point is studied by calculating interface-interface interactions using an expansion in inverse spin anisotropy.File in questo prodotto:
