A new two-mode thermo-and squeezing-mixed optical field

摘要

We propose a new two-mode thermo-and squeezing-mixed optical field,described by the new density operator p =(1-ef-|g|2) ega(+)b(+) efa(+)a |0>bb <0| eg*ab,where |0>bb <0| is the b-mode vacuum,efa(+)a represents the thermo-field,and ega(+)b(+) indicates squeezing.The photon statistics for p is studied by virtue of the method of integration within ordered product (IWOP) of operators.Such a field can be generated when a two-mode squeezed state passes through a one-mode dissipation channel.
