摘    要:本文构造了由两不同奇相干态组成的第Ⅲ种四态叠加多模叠加态光场|Ψo(4),Ⅲ>q.利用新近建立的多模压缩态理论,详细研究了态|Ψo(4),Ⅲ>q的广义非线性等阶N次方Y压缩特性,结果发现由不呈现等阶高阶压缩效应的两奇相干态线性叠加组成的新量子光场态|Ψo(4),Ⅲ>q呈现出许多奇异物理现象:1)当压缩阶数N=4m(m=1,2,3,…,…)时,态|Ψo(4),Ⅲ>q始终恒处于等阶N-Y最小测不准态;2)当压缩阶数N=4m-2(m=1,2,3,…,…)时,在一定条件下,态|Ψo(4),Ⅲ>q的某一正交分量处于等阶N-Y最小测不准态时,另一正交分量则始终既不处于等阶N-Y最小测不准态,也不呈现等阶N次方Y压缩效应,这种现象称为“半相干态”效应;在另外一些条件下,态|Ψo(4),Ⅲ>q的两正交分量可分别呈现出等阶N次方Y压缩效应,其压缩特性具有周期性变化的、互补对称的关系.3)当压缩阶数N为奇数时,态|Ψo(4),Ⅲ>q始终不会呈现等阶N次方Y压缩效应,也不处于等阶N-Y最小测不准态,但在一定条件下可呈现“半相干态”效应.

关 键 词:四态叠加  多模叠加态光场  多模虚奇相干态  多模奇相干态  等阶N-Y最小测不准态  等阶N次方Y压缩  “半相干态”

Abstract:According to the linear superimposition principle in quantum mechanics,the third four-state superimposition multimode superimposition light field |Ψo(4),Ⅲ>q composed by two different odd coherent state |Ψ,o>q and |Ψ (2) i,o>q Based on the multimode squeezed state theory,the properties of equal N-th power Y-squeezing of the state |Ψo(4),Ⅲ>q is studied,and it is found that:1)when N=4m(m=1,2,3,…,…),the state |Ψo(4),Ⅲ>q always stayed in equal-order N-Y minimum uncertainty state;2)when N=4m-2(m=1,2,3,…,…),under some conditions,while one quadrature component of the state |Ψo(4),Ⅲ>q appears as equal-order N-Y minimum uncertainty state,the other quadrature component appears neighter as equal-order N-th power Y-squeezing action nor as equal-order N-Y minimum uncertainty state,thus,the state |Ψo(4),Ⅲ>q appears as “half coherent state”;under otherdifferent conditions,the state |Ψo(4),Ⅲ>q appears as equal-order N-th power Y-squeezing action,and the squeezed properties of two quadrature components has periodic changeable and complimantary relationship 3)when N is an odd number,the state |Ψo(4),Ⅲ>q alawys appears neither as equal-order N-th power Y-squeezing action nor as equal-order N-Y minimum uncertainty state,but,under some conditions,appears as “half coherent state”.
Keywords:Four  state superimposition  Multimode superimposition state light field  Multimode odd coherent state  Multimode imaginary odd coherent state  Equal  order N  Y minimum uncertainty state  Equal  order N  th power Y  squeezing  Half coherent state
