Influence of radiative damping on the optical-frequency susceptibility

چکیده
Motivated by recent discussions concerning the manner in which damping appears in the electric polarizability, we show that a there is a dependence of the nonresonant contribution on the damping and that b the damping enters according to the ‘‘opposite sign prescription.’’ We also discuss the related question of how the damping rates in the polarizability are related to energy-level decay rates.

In this research, the modal parameters of a beam in free-free condition are extracted by performing different experiments in laboratory. For this purpose, two different techniques are employed. The first methodology is considered as a time domain method in Operational Modal Analysis. While the other one is frequency domain impact hammer test which is categorized as an Experimental Modal Analysi...

This paper investigates damping ratio in micro-beam resonators based on magneto-thermo-elasticity. A unique aspect of the present study is the effect of permanent magnetic field on the stiffness and thermo-elastic damping of the micro resonators. In our modeling the theory of thermo-elasticity with interacting of an externally applied permanent magnetic field is taken into account. Combined the...
متن کاملDrastic effects of damping mechanisms on the third-order optical nonlinearity
We have investigated the optical response of superradiant atoms, which undergoes three different damping mechanisms: radiative dissipation (γr), dephasing (γd), and nonradiative dissipation (γn). Whereas the roles of γd and γn are equivalent in the linear susceptibility χ , the third-order nonlinear susceptibility χ drastically depends on the ratio of γd and γn: When γd ≪ γn, χ (3) is essential...

Slow magneto-acoustic waves are often observed in polar plumes and active region fan loops. The observed periodicities of these waves are in the range of 1- 40 minutes. Mainly, the ratio of damping time to the oscillation period is less than 2 (equal to the ratio damping length to the wave length), which corresponds to the strong damping regime. In general, slow magneto-acoustic waves can be da...
