Description

The Hartree-Fock-Bogoliubov method performs the one-particle approximation in a theory of Bose-Einstein condensation (BEC). This paper is devoted to the treatment of two cases: superfluid 4He in porous media and atomic BEC in traps subjected to the gravitational field. Both these systems show the dependence of a critical BEC temperature on their non-uniform properties in space

Abstract (Russian)

Метод Хартри-Фока-Боголюбова выполняет функции одночастичного приближения в теории конденсации Бозе-Эйнштейна (КБЭ). Эта статья посвящена рассмотрению двух случаев: сверхтекучий 4He в пористой среде и атомарная КБЭ в ловушках при воздействии гравитационного поля. Обе эти системы обнаруживают зависимость критической КБЭ температуры от их неоднородных свойств в пространстве
