“…Over the last few years, beat wave excitation and heating of plasma as well as nanocluster plasma has been a particular field of interest due to its diverse applications in current drive experiments, terahertz radiation generation, acceleration of charge particles and diagnostics [1][2][3][4][5][6][7][8]. Although earlier studies of plasma excitations have been performed by several groups [9][10][11][12], a cluster adds new quantities to so called surface plasmons that enhance the excitation efficiency [13].…”

In this present theoretical study, we investigate electron Bernstein wave (EBW) aided collisional nanocluster plasma heating by nonlinear interaction of two super-Gaussian laser beams. The interactions of laser beams electric field profiles with electronic clouds of nanoclusters cause the beat wave. The nonlinear ponderomotive force is generated through the beat wave. There may be good potential to excite the EBW aiding cluster plasma to lead electron heating via cyclotron damping of the Bernstein wave. An analytical scheme is proposed for the anomalous heating and evolution of electron temperature by using this mechanism. Graphical discussions were promised to achieve extreme heating rate via the spatial shape of super-Gaussian laser beams and the resonance condition of beat wave to surface plasmon frequency. The heating is controlled by tuning the laser beam width, mode index, collisional frequency, clustered radius, and density.
