A New Monte-Carlo Radiative Transfer Simulation of Cyclotron Resonant Scattering Features
Sandeep Kumar, Suman Bala, Dipankar Bhattacharya
We present a new Monte-Carlo radiative transfer code, which we have used to model the cyclotron line features in the environment of a variable magnetic field and plasma density. Th…
Ionization and transport in partially ionized multicomponent plasmas: Application to atmospheres of hot Jupiters
Sandeep Kumar, Anna Julia Poser, Manuel Schöttler +5
We study ionization and transport processes in partially ionized multicomponent plasmas. The plasma composition is calculated via a system of coupled mass action laws. The electron…
Interplay of single particle and collective response in molecular dynamics simulation of dusty plasma system
Srimanta Maity, Amita Das, Sandeep Kumar +1
Collective response of the plasma medium is well known and has been explored extensively in several contexts. The single particle response is typically treated as collisional inter…
Spiral waves in driven strongly coupled Yukawa systems
Sandeep Kumar, Amita Das
Spiral wave formations are ubiquitous in nature. In the present paper, the excitation of spiral waves in the context of driven two-dimensional dusty plasma (Yukawa system) has been…
Spiral Waves in Driven Dusty Plasma Medium: Generalized Hydrodynamic Fluid Description
Sandeep Kumar, Bhavesh Patel, Amita Das
Spiral waves are observed in many natural phenomena. They have been extensively represented by the mathematical FitzHugh-Nagumo (FHN) model [Barkley et al., Phys. Rev. A 42, 2489 (…
Observation of the Korteweg-de Vries soliton in molecular dynamics simulations of a dusty plasma medium
Sandeep Kumar, Sanat Kumar Tiwari, Amita Das
The excitation and evolution of Korteweg-de Vries (KdV) solitons in a dusty plasma medium are studied using Molecular Dynamics (MD) simulations. The dusty plasma medium is modelled…
