The order parameter and susceptibility of the 3D Ising-like system in an external field near the phase transition point
The present work is devoted to the investigation of the 3D Ising-like model in the presence of an external field in the vicinity of critical point. The method of collective variables is used. General expressions for the order parameter and susceptibility are calculated as functions of temperature an...

Досліджено тривимірну ізингоподібну модель поблизу критичної точки за наявності зовнішнього поля. Використано метод колективних змінних. Розраховано загальні вирази для параметра порядку та сприйнятливості системи як функції температури та зовнішнього поля, а також скейлінгові функції цих величин одержано в явному вигляді. Зроблено порівняння з результатами, що одержано в межах параметричного представлення рівняння стану та за допомогою методів Монте Карло симуляцій. Запропоновано та використано у процесі обчислень новий вираз для точки виходу з критичного режиму флуктуацій параметра порядку. 2010 Article The order parameter and susceptibility of the 3D Ising-like system in an external field near the phase transition point / M.P.
