Dynamically phase-separated states in driven binary dusty plasma
Farida Batool, Sandeep Kumar, Sanat Kumar Tiwari
We comprehensively study external forcing-driven dynamical structure formation in a binary dusty plasma mixture. Using two-dimensional driven-dissipative molecular dynamics simulat…
Nonlinear dispersion relation of dust acoustic waves using the Korteweg-de Vries model
Farida Batool, Ajaz Mir, Sanat Tiwari +1
In this brief communication, we present an exact analytic nonlinear dispersion relation (NLDR) for the dust acoustic waves using the Korteweg-de Vries (KdV) model. The NLDR agrees…
Synchronization of Dust Acoustic Waves in a forced Korteweg-de Vries-Burgers model
Ajaz Mir, Sanat Tiwari, Abhijit Sen +3
The synchronization of dust acoustic waves to an external periodic source is studied in the framework of a driven Korteweg-de Vries-Burgers equation that takes into account the app…
Bispectral analysis of nonlinear mixing in a periodically driven Korteweg-de Vries system
Ajaz Mir, Sanat Tiwari, Abhijit Sen
The nonlinear response of a periodically driven Korteweg-de Vries model system is studied using a variety of nonlinear drivers and compared to previous results obtained for a purel…
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…
Reduction of electron heating by magnetizing ultracold neutral plasma
Sanat Kumar Tiwari, Scott D. Baalrud
Electron heating in an ultracold neutral plasma is modeled using classical molecular dynamics simulations in the presence of an externally applied magnetic field. A sufficiently st…
Pair Correlation Functions of Strongly Coupled Two-Temperature Plasma
Nathaniel R. Shaffer, Sanat Kumar Tiwari, Scott D. Baalrud
Using molecular dynamics simulations, we perform the first direct tests of three proposed models for the pair correlation functions of strongly coupled plasmas with species of uneq…
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…
Thermodynamic State Variables in Quasi-Equilibrium Ultracold Neutral Plasma
Sanat Kumar Tiwari, Nathaniel R. Shaffer, Scott D. Baalrud
The pressure and internal energy of an ultracold plasma in a state of quasi-equilibrium are evaluated using classical molecular dynamics simulations. Coulomb collapse is avoided by…
Wakes and precursor soliton excitations by a moving charged object in a plasma
Sanat Kumar Tiwari, Abhijit Sen
We study the evolution of nonlinear ion acoustic wave excitations due to a moving charged source in a plasma. Our numerical investigations of the full set of cold fluid equations g…
Visco-elastic fluid simulations of coherent structures in strongly coupled dusty plasma medium
Vikram Singh Dharodi, Sanat Kumar Tiwari, Amita Das
A generalized hydrodynamic (GHD) model depicting the behaviour of visco-elastic fluids has often been invoked to explore the behaviour of a strongly coupled dusty plasma medium bel…
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…
Exact propagating nonlinear singular disturbances in strongly coupled dusty plasmas
Amita Das, Sanat Kumar Tiwari, Predhiman Kaw +1
The nonlinear longitudinal response of a strongly coupled dusty plasma system is analytically investigated using the Generalized Hydrodynamic (GHD) model. It is shown that the Gali…
