非平衡热场动力学中相对论中性标量场的正则量子化

Canonical Quantization for a Relativistic Neutral Scalar Field in Non-equilibrium Thermo Field Dynamics

Yuichi Mizutani, Tomohiro Inagaki, Yusuke Nakamura, Yoshiya Yamanaka

摘要:

研究了非平衡热场动力学中的相对论中性标量场。正则量子化应用于非平衡场。由于热Bogoliubov变换变得与时间有关,普通的无扰创建和湮灭运营商的运动方程进行了修改。这迫使我们在相互作用哈密顿量中引入一个热计数器项,产生额外的辐射修正。在总辐射修正项上加上自洽重整化条件,得到了相对论标量场的量子Boltzmann方程。

英文摘要:

A relativistic neutral scalar field is investigated in non-equilibrium thermo field dynamics. The canonical quantization is applied to the fields out of equilibrium. Because the thermal Bogoliubov transformation becomes time-dependent, the equations of motion for the ordinary unperturbed creation and annihilation operators are modified. This forces us to introduce a thermal counter term in the interaction Hamiltonian which generates additional radiative corrections. Imposing the self-consistency renormalization condition on the total radiative corrections, we obtain the quantum Boltzmann equation for the relativistic scalar field.
