Query: M Times Photon Subtraction-Addition Coherent Superposition Operated
  Odd-Schr\H{o}dinger-cat State: Nonclassicality and Decoherence   We introduce a new non-Gaussian state, generated by m times coherent
superposition operation $a\cos \theta +a^{\dagger }e^{i\varphi }\sin \theta $
(MCSO) on odd-Schrodinger-cat state (OSCS). Its normalized constant is turned
out to be related with the Hermite polynomial. We further investigate the
nonclassical properties of the MCSO-OSCS through Mandel's Q-parameter,
quadrature squeezing, the photocount distribution and Wigner function (WF). It
is shown that the nonclassicality of the MCSO-OSCS is influenced by the number
of times (m) of coherent superpositon operation, the angle $\theta $ and the
amplitude of the coherent state (|$\alpha _{0}$|). Especially the volume of
negative region of WF increases with the increment of parameters m, $\theta $
and $\alpha _{0}$. We also investigate the decoherence of the MCSO-OSCS in
terms of the fadeaway of the negativity of WF in a thermal environment.
