平衡态Background Radiation中平移-旋转运动纳米粒子的辐射与动力学

Radiation and Dynamics of Nanoparticle in Equilibrium Background Radiation upon Translational-Rotational Motion

G. V. Dedkov, A. A. Kyasov

摘要:

本文给出了可极化小粒子在一定温度的平衡辐射背景(热化光子气体)中作旋-转运动时,线速度和角速度矢量的任意相对取向时的辐射强度和切向力的一般表达式。结果表明,在冷真空背景下,粒子的平动速度与时间无关,粒子的自发发射强度由粒子的角速度和极化率的虚部决定。

英文摘要:

We have obtained general expressions for the intensity of radiation and tangential force of a small polarizable particle in the process of translational-rotational motion in equilibrium radiation background (thermalized photon gas) of certain temperature at an arbitrary relative orientation of the linear and angular velocity vectors. It is shown that in cold vacuum background the translational velocity of particle is independent of time and the intensity of its spontaneous emission is determined by the angular velocity and imaginary part of the polarizability.
