Mapping the complete evolution of magnetic excitation in beam-plasma system driven by an ultra-intense, femtosecond laser
Moniruzzaman Shaikh, Amit D Lad, Devshree Mandal +4
Plasmas are beset with instabilities of all types, hydrodynamic, magneto-hydrodynamic, and electromagnetic. These instabilities are complex, occur over a large range of temporal an…
Ion heating in Laser interacting with magnetized plasma
Rohit Juneja, Trishul Dhalia, Laxman Prasad Goswami +3
The ion heating mechanism in the context of laser interacting with plasma immersed in a strong magnetic field is studied. The magnetic field is chosen to be strong for laser electr…
Localized absorption of laser energy in X-mode configuration of magnetized plasma
Ayushi Vashistha, Devshree Mandal, Srimanta Maity +1
The heating of ions via lower hybrid waves has been observed in several astrophysical as well as laboratory plasmas. We have conducted Particle-In-Cell simulations to demonstrate a…
Mode conversion and laser energy absorption by plasma under an inhomogeneous external magnetic field
Srimanta Maity, Laxman Prasad Goswami, Ayushi Vashistha +2
The interaction of a high-frequency laser with plasma in the presence of an inhomogeneous external magnetic field has been studied here with the help of Particle-In-Cell simulation…
Ponderomotive force driven mechanism for electrostatic wave excitation and energy absorption of Electromagnetic waves in overdense magnetized plasma
Laxman Prasad Goswami, Srimanta Maity, Devshree Mandal +2
The excitation of electrostatic waves in plasma by laser electromagnetic pulse is important as it provides a scheme by which the power from the laser electromagnetic (EM) field can…
Electromagnetic wave transparency of X mode in strongly magnetized plasma
Devshree Mandal, Ayushi Vashistha, Amita Das
An Electromagnetic (EM) pulse falling on a plasma medium from vacuum can either reflect or propagate inside the plasma depending on whether it is overdense or underdense. In a magn…
Harmonic generation in the interaction of laser with a magnetized overdense plasma
Srimanta Maity, Devshree Mandal, Ayushi Vashistha +2
The mechanism of harmonic generation in both O and X-mode configurations for a magnetized plasma has been explored here in detail with the help of Particle-In-Cell (PIC) simulation…
Excitation of lower hybrid and magneto-sonic perturbations in laser plasma interaction
Ayushi Vashistha, Devshree Mandal, Amita Das
Lower hybrid (LH) and magneto-sonic (MS) waves are well known modes of magnetized plasma. These modes play important roles in many phenomena. The lower hybrid wave is often employe…
Spontaneous formation of magnetic dipoles by interaction of intense laser with overdense plasma
Devshree Mandal, Ayushi Vashistha, Amita Das
When a laser field is incident on an overdense plasma it is unable to penetrate inside it. Nevertheless, a part of its energy gets transferred to the electrons through a variety of…
Effect of Transverse Beam Size on the Wakefields and Driver Beam Dynamics in Electron Beam Driven Plasma Wakefield Acceleration
Ratan Kumar Bera, Devshree Mandal, Amita Das +1
In this paper, wakefields driven by a relativistic electron beam in a cold homogeneous plasma is studied using 2-D fluid simulation techniques. It has been shown that in the limit…
A new mechanism of direct coupling of laser energy to ions
Ayushi Vashistha, Devshree Mandal, Atul Kumar +2
The well-known schemes (e.g. Brunel, resonance absorption, JxB heating etc.) couple laser energy to the lighter electron species of the plasma. In this work, a fundamentally new me…
