Summary
The properties of a many-body system exhibiting condensation both in a periodic state and in an homogeneous state are compared. The possibility of a transition between these two phases is discussed and explicitly shown to exist in a model.
Riassunto
Sono state confrontate le proprietà di un sistema di molti bosoni presentante condensazioni sia in uno stato periodico che in uno stato omogeneo. La possibilità di avere transizioni da una fase all’altra è discussa ed esplicitamente mostrata in un modello.
Реэюме
Сравниваются свойства многочастичной системы, обнаруживаюшей конденсацию как в периодическое состояние, так и в однородное состояние. Обсуждается воэможность перехода между двумя зтими фаэами, и аккуратно покаэывается сушествование зтой воэможности на модели.
