Название: Low-Temperature Analysis of the ANNNI Model in an External Magnetic Field: Cascades of Phase Transitions, Complete Devil's Staircases
Автор: Uimin G.
Аннотация:
The behavior of the axial next-nearest-neighbor Ising (ANNNI) model in an external magnetic field is investigated using a low-temperature expansion of the free energy. Unusual cascades of phase transitions and "complete devil's stair-cases," unexpected for the ANNNI model, are found.
