摘要提出了一类新的偶（奇）罗盘态（Wigner cat态的特定叠加）的生成方案[a]。Dehghani等人，安。物理学报，362,659(2015)])，在宇称变形的jayes - cummings hamilton量存在下[A]。Dehghani et al., Sci。Rep.6, 38069(2016)]描述了一个由连续外经典场辅助的两能级原子和腔场组成的耦合系统。特别注意通过曼德尔参数和正交压缩分析了它们的非经典性质。将维格纳参数为零时的维格纳罗盘状态与普通罗盘状态进行了比较。同时，通过一种新引入的光子加罗经态的激发，引入了广义光子加罗经态。结合后一种情况的统计分析，提出了一种新的编制理论框架。图形抽象
AbstractWe proposed a scheme to generate new class of even(odd) compass states (specific superpositions of Wigner cat states [A. Dehghani et al., Ann. Phys.362, 659 (2015)]), in the presence of the parity deformed Jaynes–Cummings Hamiltonian [A. Dehghani et al., Sci. Rep.6, 38069 (2016)] describing a coupled system comprising a two-level atom and a cavity field assisted by a continuous external classical field. Particular attention was given to analyze their non-classical properties through of the Mandel’s parameter and quadrature squeezing. The Wigner compass states (WCSs) are compared with the ordinary ones, when the Wigner parameter becomes zero. Meanwhile generalized photon added compass states (PAWCSs) were introduced, by excitations of a newly introduced WCSs. Along with statistical analysis of latter case, a new theoretical framework for preparing them is suggested.Graphical abstract
