SU(2)q-奇偶相干叠加态的非经典效应
The Nonclassical Properties of the Superposed States of SU(2) of the Odd and Even q-coherent States
【摘要】 由一维线性谐振子引入q-形变谐振子,构成q-形变谐振子的量子Heisenberg-Weyl代数,构造了SU(2)q-奇偶相干叠加态,计算了在此态下的期望值,通过理论计算作图研究了其非经典效应.发现由于形变参数的影响,其压缩效应和反聚束效应具有丰富的结构.
【Abstract】 The qdeformed harmonic oscillator is introduced from one dimension harmonic oscillator,to constitute the quantum HeisenbergWel algebra.The superposed states of SU(2)′s odd and even qcoherent states are constructed and the expectation values for these states are calculated.The noncl assical properties are studied by calculating and ploting.It is found that their squeezing and anti bunching effects have plentiful structures due to the influence of the deformation parameters.
