Transmission statistics in nonconservative disordered optical medium
Zhong Yuan Lai, Oleg Zaitsev
We determine the cumulants of electromagnetic energy transmitted through one-dimensional disordered medium with absorption or amplification. For this purpose we derive the Keldysh…

Nonlinear sigma model for optical media with linear absorption or gain
Zhong Yuan Lai, Oleg Zaitsev
In the framework of the Keldysh technique, we formulate the nonlinear sigma model for disordered optical media with linear absorption or gain. The effective action for fluctuations…
