Collective dynamics of globally delay-coupled complex Ginzburg-Landau oscillators
Bhumika Thakur, Abhijit Sen
The effect of time-delayed coupling on the collective behavior of a population of globally coupled complex Ginzburg-Landau (GCCGL) oscillators is investigated. A detailed numerical…
Two-photon decay of P-wave positronium: a tutorial
Abhijit Sen, Zurab K. Silagadze
A detailed exposition of two-photon decays of P-wave positronium is given to fill an existing gap in the pedagogical literature. Annihilation decay rates of P-wave positronium are…
Experimental Observation of a Dusty Plasma Crystal in the Cathode Sheath of a DC Glow Discharge Plasma
M. G. Hariprasad, P. Bandyopadhyay, Garima Arora +1
Dusty plasma crystals have traditionally been observed and studied in radio frequency (RF) discharge plasmas and their formation in a DC glow discharge plasma remains experimentall…
Recurrence in three dimensional magnetohydrodynamic plasma
Rupak Mukherjee, Rajaraman Ganesh, Abhijit Sen
We report on a numerical observation of recurrence phenomenon in a three dimensional magneto-hydrodynamic (MHD) plasma for certain classes of initial flow profiles. Our simulations…
Coherent nonlinear oscillations in magnetohydrodynamic plasma
Rupak Mukherjee, Rajaraman Ganesh, Abhijit Sen
Single fluid magnetohydrodynamic (MHD) equations have been studied through direct numerical simulations (DNS) using pseudo-spectral methods in two as well as three spatial dimensio…
Plasma density and ion energy control via driving frequency and applied voltage in a low pressure capacitively coupled plasma discharge
Sarveshwar Sharma, Abhijit Sen, N. Sirse +2
The dynamical characteristics of a single frequency low pressure capacitively coupled plasma (CCP) device under varying applied RF voltages and driving frequencies are studied usin…
