摘要:

An alternative derivation of the disentanglement formulas for exponential operators, also known as the Baker–Campbell–Housdorff formulas is given for several Lie algebras. The method is especially suited to Lie algebras having no nontrivial center. We also look at some results that can be obtained by the use of these formulas in the case of squeezed coherent states.
