We present a simulation of Casimir field generation in the 1D cavity with moving walls and arbitrary variation of boundary conditions. We design a numerical scheme based on the finite element method and compare photon generation due to variation of the geometry of the cavity and due to perturbation of the boundary conditions.

Мы представляем моделирование генерации поля Казимира в одномерном резонаторе с подвижными стенками и произвольным изменением граничных условий. Мы разрабатываем численную схему на основе метода конечных элементов и сравниваем генерацию фотонов за счет изменения геометрии резонатора и за счет возмущения граничных условий.
