Revisiting Electron Heating in Capacitively Coupled Plasma (CCP) Discharges: A Nonlinear Dynamics Perspective
Rishabh Singh, Sarveshwar Sharma, Bhooshan Paradkar +1
Despite decades of research, the electron heating mechanisms in capacitively coupled plasma (CCP) discharges over a wide range of operating conditions is not fully understood. Alth…
Quasi-static transverse electric field driven electron acceleration in relativistic laser matter interaction
Ameya Parab, Bhooshan Paradkar, Aparajit C. +4
Achieving significant energy gain in laser-driven relativistic electron beams remains challenging due to dephasing between the accelerating laser field and the electrons. We show t…
Collisionless Bulk Electron Heating in Resonant Low-Voltage Capacitively Coupled Plasmas
Sarveshwar Sharma, Igor D. Kaganovich, Animesh Kuley +3
We investigate collisionless power absorption in resonant, lowpressure capacitively coupled plasmas (CCPs). In these radio-frequency (RF) discharges, the sheath capacitance almo…
Particle Dynamics in Constant Synthetic Non-Abelian Fields
Subramanya Bhat K. N., Amita Das, V Ravishankar +1
Yang-Mills theory has extended well beyond its original role in describing the strong force and now emerges as an effective theory in condensed matter, ultracold atomic, and photon…
Multigrid Poisson Solver for Complex Geometries Using Finite Difference Method
Deepak Gautam, Bhooshan Paradkar
We present an efficient numerical method, inspired by transformation optics, for solving the Poisson equation in complex and arbitrarily shaped geometries. The approach operates by…
