Kelvin-Helmholtz instability in strongly coupled dusty plasma with rotational shear flows and tracer transport
Vikram Dharodi, Bhavesh Patel, Amita Das
Kelvin-Helmholtz (KH) instability plays a significant role in transport and mixing properties of any medium. In this paper, we numerically explore this instability for a two-dimens…
Excitation of Electrostatic Standing Wave in the Superposition of Two Counter Propagating Relativistic Whistler Waves
Mithun Karmakar, Sudip Sengupta, Bhavesh Patel
The problem of standing wave formation by superposing two counter-propagating whistler waves in an overdense plasma, studied recently by Sano et al. (Phys. Rev. E 100, 053205 (2019…
A 3D Magnetohydrodynamic simulation for the propagation of plasma plume transverse to applied magnetic field
Bhavesh G. Patel, Narayan Behera, R. K. Singh +2
We have carried out a 3D ideal-MHD (Magnetohydrodynamic) simulation to study the evolution of laser generated plasma plume in a moderate external magnetic field (0.13 T) oriented p…
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…
Evidence of new finite beam plasma instability for magnetic field generation
Amita Das, Atul Kumar, Chandrasekhar Shukla +8
We demonstrate by computer simulations, laser plasma experiments, and analytic theory that a hitherto unknown instability is excited in the beam plasma system with finite transvers…
Merger and reconnection of Weibel separated relativistic electron beam
Chandrasekhar Shukla, Atul Kumar, Amita Das +1
The relativistic electron beam (REB) propagation in a plasma is fraught with beam plasma instabilities. The prominent amongst them being the collisionless Weibel destabilization wh…
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 1-D time dependent non-propagating laser plasma structures using Fluid and PIC codes
Deepa Verma, Ratan Kumar Bera, Atul Kumar +2
The manuscript reports the observation of time dependent localized and non-propagating structures in the coupled laser plasma system through 1-D fluid and PIC simulations. It is re…
Magnetic field generation in finite beam plasma system
Amita Das, Atul Kumar, Chandrasekhar Shukla +7
For finite systems boundaries can introduce remarkable novel features. A well known example is the Casimir effect [1, 2] that is observed in quantum electrodynamic systems. In clas…
Sub and super-luminar propagation of structures satisfying Poynting like theorem for incompressible GHD fluid model depicting strongly coupled dusty plasma medium
Vikram Dharodi, Amita Das, Bhavesh Patel +1
The strongly coupled dusty plasma has often been modelled by the Generalized Hydrodynamic (GHD) model used for representing visco-elastic fluid systems. The incompressible limit of…
Turbulence in two dimensional visco - elastic medium
Sanat Kumar Tiwari, Vikram Singh Dharodi, Amita Das +2
The properties of decaying turbulence is studied with the help of a Generalized Hydrodynamic (GHD) fluid model in the context of two dimensional visco - elastic medium such as a st…
