概要

• 論文の詳細を見る

• In order to avoid unsatisfactory points of the conventional Holstein-Primakoff representation of the su(1,1)-algebra for the description of thermal effects in many-boson or oscillating systems, the conventional from is modified. The basic idea can be found in a possible canonical transformation from the conventional to the new form. Four forms are given, and with the aid of these modified forms, it is expected to describe, for example, fluctuations around a bose-condensed state.
