Propagation and collisionless damping of topologically-protected surface plasma waves in non-uniformly magnetized plasma columns
Roopendra Singh Rajawat, Gennady Shvets
Recent theoretical studies revealed the existence of topologically-protected surface plasma waves (TSPWs) in cold magnetized plasmas assumed uniform along the direction of a uniaxi…
Nontrivial low-frequency topological waves at the boundary of a magnetized plasma
Roopendra Singh Rajawat, Tianhong Wang, Gennady Shvets
The topological properties of a magnetized cold gaseous plasma have recently been explored and the existence of topologically protected edge states has been established. These stud…
Effects of Laser Polarization on Target Focusing and Acceleration in a Laser-Ion Lens and Accelerator
Roopendra Singh Rajawat, Tianhong Wang, V. Khudik +1
We present the process of ion acceleration using ultra-thin foils irradiated by elliptically polarized, high-intensity laser pulses. Recently, efficient generation of monoenergetic…
Acceleration and focusing of multispecies ion beam using a converging laser-driven shock
Jihoon Kim, Roopendra Rajawat, Tianhong Wang +1
We demonstrate an ion acceleration scheme capable of simultaneously focusing and accelerating a multispecies ion beam with monoenergetic spectra to a few micron radius. The focal l…
Continuum damping of topologically-protected edge modes at the boundary of a magnetized plasma
Roopendra Singh Rajawat, V. Khudik, G. Shvets
Recent extension of the topological ideas to continuous systems with broken time-reversal symmetry, such as magnetized plasmas, provides new insights into the nature of scattering-…
