利用热场动力学方法,提出了具有有限温度的热克尔态,研究了这些态的量子统计性质及其与温度的关系,讨论了这些态中场振幅的涨落与压缩性质.对于热化的场,还提出了热压缩的定义,并对热克尔态,讨论了温度对热压缩的影响By making use of thermo-field dynamics(TFD),we construct the thermal Kerr states with finite temperature.We investigate the quantum statistical properties of these states and their dependence on temperature.We discuss the fluctuations of amplitude in these states and squeezing.We also introduce the definition of thermosqueezing for thermalized states and discuss the effect of temperature on thermosqueezing for thermal Kerr states.
