Generalized condensation and the Bogoliubov theory of superfluidity
In this paper we scrutinize the Bogoliubov theory of superfluidity on the level of the first Bogoliubov ansatz. This ansatz preconizes the Bogoliubov truncated Hamiltonian as a starting point of this theory. Since this ansatz is based on the hypothesis concerning the Bose-Einstein condensation in...

In this paper we scrutinize the Bogoliubov theory of superfluidity on the level of the first Bogoliubov ansatz. This ansatz preconizes the Bogoliubov truncated Hamiltonian as a starting point of this theory. Since this ansatz is based on the hypothesis concerning the Bose-Einstein condensation in zero-mode as well as on its stability with respect to interactions, we present some rigorous results, which cast doubt on this hypothesis. У цій статті ми детально досліджуємо теорію надплинності Боголюбова на рівні першого анзацу Боголюбова. Цей анзац стверджує обрізаний гамільтоніан Боголюбова як стартову точку цієї теорії. Оскільки цей анзац ґрунтується на гіпотезі стосовно Бозе-Ейнштейна конденсації в нульовій моді і на її стабільності по відношенню до взаємодії, ми представляємо строгі результати, які піддають сумніву цю гіпотезу. 2000 Article Generalized condensation and the Bogoliubov theory of superfluidity / V.A.

| description |
In this paper we scrutinize the Bogoliubov theory of superfluidity on the
level of the first Bogoliubov ansatz. This ansatz preconizes the Bogoliubov
truncated Hamiltonian as a starting point of this theory. Since this ansatz
is based on the hypothesis concerning the Bose-Einstein condensation in
zero-mode as well as on its stability with respect to interactions, we present
some rigorous results, which cast doubt on this hypothesis. |
