Alternating Screening And Higher Harmonics In Complex Plasmas

Moldabekov, Z.


Modeling properties of strongly correlated many-particle systems are of both fundamental and practical importance. At the same time, generating and probing these properties is challenging. To this end, laboratory model systems play a central role in studying correlated many-particle phenomena. In this presentation, we focus on a specific laboratory model system – dusty plasmas – to model collective particle behavior under controlled conditions. Thereby, we push the frontier of dusty plasma physics by predicting the generation of high harmonics in dusty plasmas with alternating screening length [1]. We found a simple phenomenological expression for the dispersion relation of higher harmonics. Moreover, it is shown that the periodically alternating screening causes a self-conjugate state with negative refraction. As the application, we speculate that our findings can serve as a test bed for studying the fundamental physics of a self-conjugate state with negative refraction in strongly correlated systems on the kinetic level.
