摘要
本文中我们构造了量子群SU(1,1)_q的Dyson表示,并找出了该表示与Holstein-Primakoff表示之间的变换关系,同时文中讨论了Dyson表示对应的相干态,它正是q畸变的Weyl-Heisenberg相干态.
The Dyson realization for the quantum group SU(1,1)_q is constructed and the trans-formation matrix,which turns the Dyson into the Holstein-Primakoff representation,is given. The co-herent state for the Dyson realization is discussed and found to be the q-deformed Weyl-Heisenberg co-herent state.
