Abstract:

Two types of boson-pair coherent states, which were proposed independently by the present authors, are investigated. The main conclusion is the following: Although the two states are superposed contrastively in terms of the boson-pairs, the expectation values of the boson-pair operators for these states are the same as one another with high accuracy.
