Abstract
We study the higher-order fluctuations and squeezing of quadrature operators in the squeezed thermal states. In terms of measured phase operators, we discuss the fluctuations and squeezing of phases in these states. We conclude that the condition of higher-order squeezing for quadrature components of the field is order-independent and the fluctuations of measured phase operators are temperature-independent.
