The property of twoorder unequalledpower differencesqueezingin the second multimode superposition state light field

Ju Wang

By using of general theory of unequalledpower squeezing in multimode radiation field,the property of unequalledpower difference squeezing (that is Njth power Xsqueezing) in the second kind of multimode light field state of superposition state with distinguishable two quantum states is firstly studied in detail.It is found that the second kind of multimode superposition state presents generalized nonlinear twoorder unequalledpower Njth power Xsqueezing effect that changes periodically under the certain conditions,and found the phenomenon of strange squeezing.The results demonstrate again that the multimode superposition state mentioned above is a kind of typical multimode nonclssical light field based on the document 5.

Disappearance of squeezing in superposition states and its manifestation in the energy density

Suresh Kannan, C. Sudheesh

Abstract We have classified the superposition of squeezed wavepackets into two kinds and studied their quadrature squeezing. We have shown that the squeezing and higher-order squeezing in the quadrature disappear for the states of the first kind. However, for the second kind, it is possible to achieve the maximum amount of squeezing by adjusting the parameters in the superposition. The absence of squeezing for the superposition states is explained based on the expectation value of the energy density. We find that the expectation value of energy density in quantum wavepackets that shows no squeezing is positive. We have also studied the relationship between energy density and the squeezing in the decoherence dynamics of single and two-mode squeezed states. Our further analysis shows that different types of squeezed states, including states which are not wavepackets, exhibit negative energy density.

Equal-power higher-power sum-squeezing of a kind ofmulti-mode functional superposition state light field

Yuying An

Based on the linear superposition theory in quantum mechanics, a kind of multi-mode functional superposition state light field which is made up of distinct unsymmetry five different multi-mode functional coherent states is developed. By using the mutli-mode squeezing state theory, the properties of the generalized nonlinear equal-power higher-power sum-squeezing of a kind of multi-mode functional superposition state light field is studied in detail. It is found that, under certain conditions, the first or the second perpendicular phase component of the multi-mode functional superposition state ligh field can present any generalized nonlinear equal-power higher-power sum-squeezing effect which changes periodically.
