Excitation of plasma wakefields by intense ultra-relativistic proton beam
Mithun Karmakar, Bhavesh Patel, Nikhil Chakrabarti +1
We report here an exact analytical travelling wave solution for nonlinear electron plasma wave excited by an intense ultra-relativistic proton beam. It brings out the underlying ph…
Stationary Bernstein-Greene-Kruskal structures in a current carrying relativistic cold plasma
Roopendra Singh Rajawat, Sudip Sengupta, Nikhil Chakrabarti
Nonlinear stationary structures formed in a cold plasma with immobile ions in the presence of a relativistic electron current beam have been investigated analytically in the collis…
Phase Mixing of Large Amplitude Relativistic Electron Plasma Oscillation With Inhomogeneous Ion Background
Mithun Karmakar, Chandan Maity, Nikhil Chakrabarti
Phase mixing of relativistic large amplitude nonlinear plasma wave in presence of a time independent space periodic ion density profile has been investigated. Inhomogeneous ion alo…
Excitation of plasma wakefields by proton beam
Mithun Karmakar, Sudip Sengupta, Nikhil Chakrabarti
A stationary wave solution is obtained for the proton driven plasma wake field accelerator (PDPWFA). The wake field excitation by trains of equidistant proton microbunches produced…
Experimental Observation of Electron-Acoustic Wave Propagation in Laboratory Plasma
Satyajit Chowdhury, Subir Biswas, Nikhil Chakrabarti +1
In the field of fundamental plasma waves, direct observation of electron-acoustic wave (EAW) propagation in laboratory plasmas remains a challenging problem, mainly because of heav…
New nonlinear structures in a degenerate one-dimensional electron gas
S. Ghosh, N. Chakrabarti, F. Haas
The collective dynamics of nonlinear electron waves in an one-dimensional degenerate electron gas is treated using the Lagrangian fluid approach. A new class of solutions with a no…
Viscosity gradient driven instability of `shear mode' in a strongly coupled plasma
D. Banerjee, M. S. Janaki, N. Chakrabarti +1
The influence of viscosity gradient (due to shear flow) on low frequency collective modes in strongly coupled dusty plasma is analyzed. It is shown that for a well known viscoelast…
Viscoelastic modes in a strongly coupled cold magnetized dusty plasma
Debabrata Banerjee, Janaki Sita Mylavarapu, Nikhil Chakrabarti
A generalized hydrodynamical model has been used to study low frequency modes in a strongly coupled, cold, magnetized dusty plasma. Such plasmas exhibit elastic properties due to s…
